Struct Template 

pub struct Template {
    pub roots: Vec<String>,
    pub needs_cel: bool,
    /* private fields */
}

A compiled template. Parsing is done once (at config load); rendering is per turn.

Fields

roots: Vec<String>

Every root identifier the template reads — used to fail closed on a typo’d reference at load instead of rendering a silent empty hole.

needs_cel: bool

Whether any expression needs CEL (i.e. is not a bare path).

Implementations

impl Template

pub fn parse(src: &str) -> Result<Template, String>

Parse + validate. Errors name the problem, never a byte offset alone.

pub fn reads(&self, name: &str) -> bool

Does the template read name anywhere? ({{instruction}} guard.)

pub fn render(&self, data: &Data) -> Result<String, String>

Render against data. A missing path renders empty rather than failing the turn — the load-time root check is what catches typos, and an absent-at-runtime value (no peers yet) is normal, not an error.

Trait Implementations

impl Clone for Template

fn clone(&self) -> Template

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Template

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Template

fn eq(&self, other: &Template) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
