Struct ClosureExpr 

#[non_exhaustive]
pub struct ClosureExpr<'arena, 'src> {
    pub is_static: bool,
    pub by_ref: bool,
    pub params: ArenaVec<'arena, Param<'arena, 'src>>,
    pub use_vars: ArenaVec<'arena, ClosureUseVar<'src>>,
    pub return_type: Option<TypeHint<'arena, 'src>>,
    pub body: &'arena Block<'arena, 'src>,
    pub attributes: ArenaVec<'arena, Attribute<'arena, 'src>>,
}

A closure: function() use ($x) { ... }.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

is_static: bool

true for static.

by_ref: bool

true when by reference (&).

params: ArenaVec<'arena, Param<'arena, 'src>>

Declared parameters.

use_vars: ArenaVec<'arena, ClosureUseVar<'src>>

Variables captured by use (...).

return_type: Option<TypeHint<'arena, 'src>>

Declared return type, if any.

body: &'arena Block<'arena, 'src>

Closure body.

attributes: ArenaVec<'arena, Attribute<'arena, 'src>>

#[...] attributes applied to this node.

Implementations

impl<'arena, 'src> ClosureExpr<'arena, 'src>

pub fn new(arena: &'arena Bump, body: &'arena Block<'arena, 'src>) -> Self

Builds a ClosureExpr from its identifying fields with every other field empty. Set the rest by assignment, as with Param::new.

Trait Implementations

impl<'arena, 'src> Debug for ClosureExpr<'arena, 'src>

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

Formats the value using the given formatter.

impl<'arena, 'src> Serialize for ClosureExpr<'arena, 'src>

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
