Struct templar::Template

pub struct Template(_);

Template holds the prepared result of parsing a template. Because the template does not need to be reparsed, subsequent executions come at a low cost.

Implementations

impl Template

pub fn render(&self, ctx: &impl Context) -> Result<String>

Render a template as a string.

Usage

let t = Templar::global().parse_expression("5 + 5")?;
assert_eq!(t.render(&context)?, "10");

pub fn exec(&self, ctx: &impl Context) -> Result<Document>

Execute a template, getting a Document from the unstructured crate as a result. many of the native rust types implement into() on Document making direct comparisons easy.

Usage

let t = Templar::global().parse_expression("5 + 5")?;
assert_eq!(t.exec(&context)?, 10i64);
