Struct ExprIfLet

pub struct ExprIfLet {
    pub attrs: Vec<Attribute>,
    pub if_token: If,
    pub let_token: Let,
    pub pat: Box<Pat>,
    pub eq_token: Eq,
    pub expr: Box<Expr>,
    pub then_branch: Block,
    pub else_branch: Option<(Else, Box<Expr>)>,
}

An if let expression with an optional else block: if let pat = expr { ... } else { ... }.

The else branch expression may only be an If, IfLet, or Block expression, not any of the other types of expression.

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

Trait Implementations

impl Clone for ExprIfLet

fn clone(&self) -> ExprIfLet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExprIfLet

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

Formats the value using the given formatter.

impl From<ExprIfLet> for Expr

fn from(e: ExprIfLet) -> Expr

Converts to this type from the input type.

impl Hash for ExprIfLet

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 ExprIfLet

fn eq(&self, other: &ExprIfLet) -> 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 Synom for ExprIfLet

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

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

impl ToTokens for ExprIfLet

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.

impl Eq for ExprIfLet
