pub struct Body<'hir> {
    pub params: &'hir [Param<'hir>],
    pub value: Expr<'hir>,
    pub generator_kind: Option<GeneratorKind>,
}
Expand description

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 params array containing the (x, y) pattern
  • a value containing the x + y expression (maybe wrapped in a block)
  • generator_kind would be None

All bodies have an owner, which can be accessed via the HIR map using body_owner_def_id().

Fields

params: &'hir [Param<'hir>]value: Expr<'hir>generator_kind: Option<GeneratorKind>
