Struct cairo_lang_lowering::objects::StatementMatchExtern

pub struct StatementMatchExtern {
    pub function: FunctionId,
    pub inputs: Vec<VariableId>,
    pub arms: Vec<(ConcreteVariant, BlockId)>,
    pub outputs: Vec<VariableId>,
}

A statement that calls an extern function with branches, and “calls” a possibly different block for each branch.

Fields

function: FunctionId

A concrete external function to call.

inputs: Vec<VariableId>

Living variables in current scope to move to the function, as arguments.

arms: Vec<(ConcreteVariant, BlockId)>

Match arms. All blocks should have the same rets. Order must be identical to the order in the definition of the enum.

outputs: Vec<VariableId>

New variables to be introduced into the current scope from the arm outputs.

Trait Implementations

impl Clone for StatementMatchExtern

fn clone(&self) -> StatementMatchExtern

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StatementMatchExtern

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl DebugWithDb<LoweredFormatter<'_>> for StatementMatchExtern

fn fmt(&self, f: &mut Formatter<'_>, ctx: &LoweredFormatter<'_>) -> Result

fn debug<'me, 'db>(&'me self, db: &'me Db) -> DebugWith<'me, Db>where
    Self: 'me + Sized,

fn into_debug<'me, 'db>(self, db: &'me Db) -> DebugWith<'me, Db>where
    Self: 'me + Sized,

impl PartialEq<StatementMatchExtern> for StatementMatchExtern

fn eq(&self, other: &StatementMatchExtern) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
