Enum Engine 

pub enum Engine {
    Simple,
}

Supported template engines for processing templates.

Each engine provides different features and syntax:

• Simple: Basic {variable} substitution
• Handlebars: Full Handlebars templating with helpers and conditionals
• Tera: Jinja2-like templating with filters and inheritance
• MiniJinja: Lightweight Jinja2 implementation

Examples

use tomplate_build::Engine;

// Use in Builder
Builder::new()
    .default_engine(Engine::Handlebars)
    .build()?;

Feature Flags

Some engines require feature flags to be enabled:

• handlebars: Enables the Handlebars engine
• tera: Enables the Tera engine
• minijinja: Enables the MiniJinja engine

Variants

Simple

Simple variable substitution engine.

Uses {variable} syntax for placeholders. This is the default engine and requires no additional features.

Example Template

Hello {name}, you have {count} messages.

Implementations

impl Engine

pub fn as_str(&self) -> &'static str

Returns the string representation of the engine.

This is the value used in TOML files for the engine field.

Examples

assert_eq!(Engine::Simple.as_str(), "simple");
assert_eq!(Engine::Handlebars.as_str(), "handlebars");

Trait Implementations

impl Clone for Engine

fn clone(&self) -> Engine

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Engine

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

Formats the value using the given formatter.

impl Default for Engine

fn default() -> Self

Returns the default engine (Simple).

impl<'de> Deserialize<'de> for Engine

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Engine

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

Formats the value using the given formatter.

impl FromStr for Engine

fn from_str(s: &str) -> Result<Self>

Parses an engine name from a string.

Examples

use std::str::FromStr;
use tomplate_build::Engine;

let engine = Engine::from_str("handlebars")?;
assert_eq!(engine, Engine::Handlebars);

Errors

Returns an error if the engine name is unknown or the required feature is not enabled.

type Err = Error

The associated error which can be returned from parsing.

impl PartialEq for Engine

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Engine

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Engine

impl Eq for Engine
