Struct rustc::hir::Body [−][src]
🔬 This is a nightly-only experimental API. (rustc_private
)
this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml
instead?
The body of a function, closure, or constant value. In the case of a function, the body contains not only the function body itself (which is an expression), but also the argument patterns, since those are something that the caller doesn't really care about.
Examples
fn foo((x, y): (u32, u32)) -> u32 { x + y }
Here, the Body
associated with foo()
would contain:
- an
arguments
array containing the(x, y)
pattern - a
value
containing thex + y
expression (maybe wrapped in a block) is_generator
would be false
All bodies have an owner, which can be accessed via the HIR
map using body_owner_def_id()
.
