Struct PipeNode 

pub struct PipeNode {
    pub span: Span,
    pub name: Ident,
    pub args: Vec<TokenStream>,
}

A single pipe stage in a {{ expr | pipe }} interpolation.

At expand time, the name is matched against the built-in pipe list. Unrecognised names are assumed to be custom pipe structs and are PascalCase-converted.

{{ name | snake }}          → PipeNode { name: "snake", args: [] }
{{ name | ident:"get_{}" }} → PipeNode { name: "ident", args: ["get_{}"] }

Fields

span: Span

Source span of the pipe name.

name: Ident

The pipe name as written, e.g. snake, ident, my_custom_pipe.

args: Vec<TokenStream>

Colon-separated arguments following the name.
