Struct LookupCtx 

pub struct LookupCtx<'a> {
    pub property_name: Option<&'a str>,
    pub property_type: Type,
    pub component_scope: &'a [ElementRc],
    pub diag: &'a mut BuildDiagnostics,

    pub type_register: &'a TypeRegister,
    pub type_loader: Option<&'a TypeLoader<'a>>,
    pub current_token: Option<NodeOrToken>,
}

Contains information which allow to lookup identifier in expressions

Fields

property_name: Option<&'a str>

the name of the property for which this expression refers.

property_type: Type

the type of the property for which this expression refers. (some property come in the scope)

component_scope: &'a [ElementRc]

Here is the stack in which id applies

diag: &'a mut BuildDiagnostics

Somewhere to report diagnostics

arguments: Vec<String>

The name of the arguments of the callback or function

type_register: &'a TypeRegister

The type register in which to look for Globals

type_loader: Option<&'a TypeLoader<'a>>

The type loader instance, which may be used to resolve relative path references for example for img!

current_token: Option<NodeOrToken>

The token currently processed

Implementations

impl<'a> LookupCtx<'a>

pub fn empty_context( type_register: &'a TypeRegister, diag: &'a mut BuildDiagnostics, ) -> Self

Return a context that is just suitable to build simple const expression

pub fn return_type(&self) -> &Type
