Struct Reference 

pub struct Reference { /* private fields */ }

A ${...} reference read outside a template: the field it names and the accessors that slice it, validated against the pattern’s capture names as a template’s are, so a callback reads e:domain or 0:last4 as a template renders it.

Implementations

impl Reference

pub fn parse(body: &str, bound: &[String]) -> Result<Reference, TemplateError>

Parse the body a template writes inside ${...}: 0, a register’s name or its position among bound, and the accessors after a colon.

Errors

A name the pattern binds no register under, a position past the last it binds, or an accessor that is not one.

pub fn field(&self) -> &Field

What the reference names: the whole match or one register.

pub fn apply(&self, text: &str) -> String

The accessors applied to text, left to right: text itself where there are none, and nothing where a slicing accessor finds nothing.

pub fn read<M: Spanned>(&self, m: &M, input: &[u8]) -> String

The reference read over one match: the field’s bytes, then the accessors, as a template renders ${body} there.

Trait Implementations

impl Clone for Reference

fn clone(&self) -> Self

Formats the value using the given formatter.

impl Eq for Reference
