cheap-masm-equivalents

Use when writing or reviewing MASM hot paths or loops — prefer the cheaper equivalent: loop counters and pointers on the operand stack instead of procedure locals, `neq.0` over `gt.0` for non-zero checks, `cdrop` over an `if/else` selecting between two…

Langue du texte source : anglais

masm-locals-over-globals

Use when a MASM procedure needs temporary scratch storage — keep it in procedure-local memory so it cannot collide in a shared global region.

masm-proc-type-signatures

Enforce type-signature conventions for public Miden Assembly (.masm) procedures. Use when adding, editing, or reviewing a `pub proc` signature — parameter and return types, semantic type aliases, struct/array/tuple types, and how the signature maps onto the…

masm-inline-comments

Enforce inline commenting conventions for Miden Assembly (.masm) files. Use when editing, reviewing, or creating .masm files.

Langue du texte source : anglais

masm-doc-comments

Enforce doc comment conventions for Miden Assembly (.masm) procedures. Use when editing, reviewing, or creating .masm procedures, especially when documenting inputs, outputs, panic conditions, or invocation types.

Langue du texte source : anglais

assert-specific-error-in-tests

Use when writing a Rust test that exercises a failure path or a MASM test that expects a `panic` / `assert` — assert on the specific expected error variant or error code.

Langue du texte source : anglais

checked-arithmetic

Use when writing Rust arithmetic on amounts or other quantities derived from external/user input — guard against silent overflow.

Langue du texte source : anglais

Use when naming a conversion or accessor method in Rust — follow the Rust API naming conventions for the method's cost and ownership.

Langue du texte source : anglais

decouple-component-from-storage

Use when writing a MASM procedure inside a reusable account component that accesses account storage — receive the storage slot as a parameter so the component is portable across storage layouts.

Langue du texte source : anglais

domain-newtypes-over-primitives

Use when introducing API parameters, struct fields, or return types that carry a domain value — represent them with a domain newtype that enforces their invariants.

Langue du texte source : anglais

felt-construction

Use when constructing a `Felt` from a numeric value in Rust — avoid silently truncating values that may exceed the field modulus.

Langue du texte source : anglais

intra-doc-links

Use when writing or editing a Rust doc comment that references a type, method, or module — link the reference so renames are caught by rustdoc.

Langue du texte source : anglais

lowercase-error-messages

Use when writing or editing a Rust error message, panic/assert string, or MASM `ERR_*` constant — follow the Rust convention for error-message casing and punctuation.

Langue du texte source : anglais

masm-error-constants

Use when adding or editing MASM `assert*` / `panic` instructions — give every assertion a descriptive named error code.

Langue du texte source : anglais

masm-explicit-stack-inputs

Use when defining the interface for a new MASM procedure — keep its inputs explicit on the stack so the signature reflects what it consumes.

Langue du texte source : anglais

masm-named-literals

Use when writing or editing MASM or Rust code that contains meaningful numeric literals — promote them to named constants with a single source of truth.

Langue du texte source : anglais

masm-rust-constant-parity

Use when changing a numeric or string constant in Rust or MASM that has a counterpart on the other side — keep the two definitions from drifting apart.

Langue du texte source : anglais

non-exhaustive-public-types

Use when defining a public `enum` or `struct` in a library crate that may gain variants or fields later — keep future additions from being breaking changes.

Langue du texte source : anglais

parametrize-related-tests

Use when writing two or more tests that differ only by inputs or expected outputs — collapse the duplication into parameterized cases.

Langue du texte source : anglais

preserve-error-source

Use when defining a new error variant or wrapping a lower-level error — keep the underlying error's source chain intact.

Langue du texte source : anglais

private-fields-with-accessors

Use when adding a public struct or changing a field's visibility in a Rust library crate — keep fields encapsulated so the layout can evolve without breaking callers.

Langue du texte source : anglais

return-error-not-panic

Use when writing a public Rust API, a deserialization path, or any code reachable from untrusted input — surface recoverable failures as a `Result`.

Langue du texte source : anglais

u32-assert-before-u32-ops

Use when writing MASM `u32*` instructions on values from user input or untrusted sources — ensure the operands are valid u32s first.

Langue du texte source : anglais

use-bon-builder

Use when introducing a Rust type whose constructor takes more than ~3 optional or named parameters — give it a generated builder instead of hand-written boilerplate.

Langue du texte source : anglais

use-test-fixtures

Use when a Rust or MASM test needs to construct an account, note, transaction, or other domain object — build it with the existing test fixtures.

Langue du texte source : anglais

validate-in-constructor

Use when writing or reviewing a Rust constructor, `try_new`, or builder `build` — centralize validation so every instance is valid by construction.

Langue du texte source : anglais

Enforce file structure and section ordering for Miden Assembly (.masm) files. Use when editing, reviewing, or creating .masm files.

Langue du texte source : anglais
