Struct Template 

pub struct Template { /* private fields */ }

A field-value template.

Implementations

impl Template

pub fn parse2(input: TokenStream) -> Result<Self, Error>

Parse a template from a TokenStream.

The TokenStream is typically all the tokens given to a macro.

pub fn before_literal_field_values<'a>( &'a self, ) -> impl Iterator<Item = &'a FieldValue>

Field-values that appear before the template string literal.

pub fn literal_field_values<'a>( &'a self, ) -> impl Iterator<Item = &'a FieldValue>

Field-values that appear within the template string literal.

This is a simple alternative to Template::visit_literal that iterates over the field-value holes.

pub fn has_literal(&self) -> bool

Whether the template contains a literal.

pub fn after_literal_field_values<'a>( &'a self, ) -> impl Iterator<Item = &'a FieldValue>

Field-values that appear after the template string literal.

pub fn visit_literal(&self, visitor: impl LiteralVisitor)

Visit the parts of the string literal part of the template.

Each fragment of text and field-value hole will be visited in sequence.

Given a template string like:

Some text and a {hole} and some {more}.

the visitor will be called with the following inputs:

1. visit_text("Some text and a ")
2. visit_hole("hole")
3. visit_text(" and some ")
4. visit_hole("more")
5. visit_text(".")

If the template doesn’t contain a literal then the visitor won’t be called.
