Struct BodyBuilder 

Source 
pub struct BodyBuilder {
    pub span: Span,
    pub body: ExprBody,
    pub current_block: BlockId,
    pub unwind_block: Option<BlockId>,
}
Expand description

Helper to construct a small ullbc body.

Fields§

§span: Span

The span to use for everything.

§body: ExprBody

Body under construction.

§current_block: BlockId

Block onto which we’re adding statements. Its terminator is always Return.

§unwind_block: Option<BlockId>

Block to unwind to; created on demand.

Implementations§

Source§

impl BodyBuilder

Source

pub fn new(span: Span, arg_count: usize) -> Self

Source

pub fn build(self) -> ExprBody

Finalize the builder by returning the built body.

Source

pub fn new_var(&mut self, name: Option<String>, ty: Ty) -> Place

Create a new local. Adds a StorageLive statement if the local is not one of the special ones (return or function argument).

Source

fn current_block(&mut self) -> &mut BlockData

Helper.

Source

pub fn push_statement(&mut self, kind: StatementKind)

Source

fn unwind_block(&mut self) -> BlockId

Source

pub fn call(&mut self, call: Call)

Source

pub fn insert_drop(&mut self, place: Place, fn_ptr: FnPtr)
