Struct MirFunction

pub struct MirFunction {
    pub name: String,
    pub arity: usize,
    pub return_ty: Ty,
    pub locals: PrimaryMap<MirLocalId, LocalInfo>,
    pub params: Vec<MirLocalId>,
    pub param_modes: Vec<MirOwnershipMode>,
    pub entry: MirBlockId,
    pub blocks: PrimaryMap<MirBlockId, MirBlock>,
}

Function-level MIR in CFG form.

• params are function parameter locals.
• param_modes mirrors source ownership modes for parameters.
• entry is the first block reached for execution.

Fields

name: String

User-visible function or field name.

arity: usize

Number of source parameters accepted by the function.

return_ty: Ty

Semantic return type of the function.

locals: PrimaryMap<MirLocalId, LocalInfo>

Local metadata arena for function values.

params: Vec<MirLocalId>

Local ids corresponding to incoming parameters.

param_modes: Vec<MirOwnershipMode>

Ownership modes for each incoming parameter.

entry: MirBlockId

Entry block id for the function CFG.

blocks: PrimaryMap<MirBlockId, MirBlock>

CFG blocks stored for the function.

Implementations

impl MirFunction

pub fn param_binding(&self, index: usize) -> MirParamBinding<'_>
