Struct syn::ExprLet

pub struct ExprLet {
    pub attrs: Vec<Attribute>,
    pub let_token: Let,
    pub pat: Pat,
    pub eq_token: Eq,
    pub expr: Box<Expr>,
}

A let guard: let Some(x) = opt.

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

Fields

pat: Pat

eq_token: Eq

expr: Box<Expr>

Trait Implementations

impl Clone for ExprLet

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExprLet

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

Formats the value using the given formatter.

impl From<ExprLet> for Expr

fn from(e: ExprLet) -> Expr

Converts to this type from the input type.

impl Hash for ExprLet

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl Parse for ExprLet

fn parse(input: ParseStream<'_>) -> Result<Self>

impl PartialEq<ExprLet> for ExprLet

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl ToTokens for ExprLet

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

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream

Convert self directly into a TokenStream object.
