Struct ExprFieldAccess

#[non_exhaustive]
pub struct ExprFieldAccess {
    pub attributes: Vec<Attribute>,
    pub expr: Box<Expr>,
    pub dot: Dot,
    pub expr_field: ExprField,
}

A field access.

• <expr>.<field>.

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.

attributes: Vec<Attribute>

Attributes associated with expression.

expr: Box<Expr>

The expr where the field is being accessed.

dot: Dot

The parsed dot separator.

expr_field: ExprField

The field being accessed.

Trait Implementations

impl Debug for ExprFieldAccess

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

Formats the value using the given formatter.

impl OptionSpanned for ExprFieldAccess

fn option_span(&self) -> Option<Span>

Get the optional span of the type.

impl Parse for ExprFieldAccess

fn parse(p: &mut Parser<'_>) -> Result<Self>

Parse the current item from the parser.

impl PartialEq for ExprFieldAccess

fn eq(&self, other: &ExprFieldAccess) -> 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 Spanned for ExprFieldAccess

fn span(&self) -> Span

Get the span of the type.

impl ToTokens for ExprFieldAccess

fn to_tokens( &self, context: &mut MacroContext<'_, '_, '_>, stream: &mut TokenStream, ) -> Result<()>

Turn the current item into tokens.

impl TryClone for ExprFieldAccess

fn try_clone(&self) -> Result<Self>

Try to clone the current value, raising an allocation error if it’s unsuccessful.

fn try_clone_from(&mut self, source: &Self) -> Result<(), Error>

Performs copy-assignment from source.
