Struct TemplateContext 

pub struct TemplateContext {
    pub path: HashMap<String, String>,
    pub query: HashMap<String, String>,
    pub headers: HashMap<String, String>,
    pub body: Value,
}

Lookup tables used while rendering templates.

Fields

path: HashMap<String, String>

Captured path parameters (e.g. {"id": "42"}).

query: HashMap<String, String>

Query parameters.

headers: HashMap<String, String>

Request headers. Keys are expected to be lower-cased.

body: Value

Parsed JSON request body (Value::Null when the body was not JSON).

Implementations

impl TemplateContext

pub fn new() -> Self

Build an empty context.

pub fn lookup(&self, expression: &str) -> Option<String>

Resolve an expression to a string value.

The expression may be:

• a helper function name (with or without arguments),
• path.<key>, query.<key>, header.<key>, or
• body.<json.path> (dot navigation through objects/arrays).

Returns None when the expression is unknown or the value is absent. Helper functions never return None.

Trait Implementations

impl Clone for TemplateContext

fn clone(&self) -> TemplateContext

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TemplateContext

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

Formats the value using the given formatter.

impl Default for TemplateContext

fn default() -> TemplateContext

Returns the “default value” for a type.
