Trait DataContext

pub trait DataContext<'a> {
    // Required methods
    fn data<D: Any + Send + Sync>(&self) -> Result<&'a D>;
    fn data_unchecked<D: Any + Send + Sync>(&self) -> &'a D;
    fn data_opt<D: Any + Send + Sync>(&self) -> Option<&'a D>;
}

Data related functions of the context.

Required Methods

fn data<D: Any + Send + Sync>(&self) -> Result<&'a D>

Gets the global data defined in the Context or Schema.

If both Schema and Query have the same data type, the data in the Query is obtained.

Errors

Returns a Error if the specified type data does not exist.

fn data_unchecked<D: Any + Send + Sync>(&self) -> &'a D

Gets the global data defined in the Context or Schema.

Panics

It will panic if the specified data type does not exist.

fn data_opt<D: Any + Send + Sync>(&self) -> Option<&'a D>

Gets the global data defined in the Context or Schema or None if the specified type data does not exist.

Object Safety

This trait is not object safe.
