Struct ExprWhileLet 

pub struct ExprWhileLet {
    pub attrs: Vec<Attribute>,
    pub label: Option<Label>,
    pub while_token: While,
    pub let_token: Let,
    pub pat: Box<Pat>,
    pub eq_token: Eq,
    pub expr: Box<Expr>,
    pub body: Block,
}

A while-let loop: while let pat = expr { ... }.

This type is available if Syn is built with the "full" feature.

Fields

attrs: Vec<Attribute>

label: Option<Label>

while_token: While

let_token: Let

pat: Box<Pat>

eq_token: Eq

expr: Box<Expr>

body: Block

Trait Implementations

impl Clone for ExprWhileLet

fn clone(&self) -> ExprWhileLet

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExprWhileLet

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

Formats the value using the given formatter.

impl Eq for ExprWhileLet

impl From<ExprWhileLet> for Expr

fn from(e: ExprWhileLet) -> Expr

Converts to this type from the input type.

impl Hash for ExprWhileLet

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ExprWhileLet

fn eq(&self, other: &ExprWhileLet) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl StructuralPartialEq for ExprWhileLet

impl Synom for ExprWhileLet

Available on crate feature full only.

fn parse(i: Cursor<'_>) -> PResult<'_, Self>

fn description() -> Option<&'static str>

impl ToTokens for ExprWhileLet

Available on crate feature full only.

fn to_tokens(&self, tokens: &mut Tokens)

Write self to the given Tokens.

fn into_tokens(self) -> Tokens

where Self: Sized,

Convert self directly into a Tokens object.
