Struct rustc_middle::mir::Location

pub struct Location {
    pub block: BasicBlock,
    pub statement_index: usize,
}

⚙️ This is an internal compiler API. (rustc_private)

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

Location represents the position of the start of the statement; or, if statement_index equals the number of statements, then the start of the terminator.

impl Location

pub const START: Location

pub fn successor_within_block(&self) -> Location

This crate is being loaded from the sysroot, a permanently unstable location for private compiler dependencies. It is not intended for general use. Prefer using a public version of this crate from crates.io via Cargo.toml.

Returns the location immediately after this one within the enclosing block.

Note that if this location represents a terminator, then the resulting location would be out of bounds and invalid.

pub fn is_predecessor_of<'tcx>(
    &self,
    other: Location,
    body: &Body<'tcx>
) -> bool

Returns true if other is earlier in the control flow graph than self.

    &self,
    other: Location,
    dominators: &Dominators<BasicBlock>
) -> bool
