Struct InterpNode 

pub struct InterpNode {
    pub span: Span,
    pub expr: TokenStream,
    pub pipes: Vec<PipeNode>,
}

An interpolation expression: {{ expr }} or {{ expr | pipe | ... }}.

The expression is evaluated at expand time and emitted into the output token stream, optionally transformed through a chain of PipeNodes.

Fields

span: Span

Source span of the {{ ... }} delimiters.

expr: TokenStream

The expression to interpolate, e.g. name or field.ty.

pipes: Vec<PipeNode>

Pipe transforms applied in order, e.g. [snake, ident:"get_{}"].
