Struct DynamicTemplate 

pub struct DynamicTemplate { /* private fields */ }

A parsed {{var}} template with an open set of named variables.

Implementations

impl DynamicTemplate

pub fn parse(template: &str) -> Self

Parse a template string. Parsing is lenient and never fails: malformed {{ / }} runs and invalid names are kept as literal text.

pub fn variables(&self) -> BTreeSet<String>

Return the sorted set of variable names referenced by the template.

pub fn render<F>(&self, lookup: F) -> Result<String, TemplateError>

where F: FnMut(&str) -> Option<String>,

Render the template, resolving each variable via lookup. A variable with no value yields TemplateError::MissingVariable.
