}Expand description
Conversion from JSON syntax, with code mapping info.
This trait is very similar to TryFrom<Value> but also passes code
code mapping info to the conversion function.

Sourcefn try_from_json_at(
value: &Value,
code_map: &CodeMap,
offset: usize,
) -> Result<Self, Self::Error>
fn try_from_json_at( value: &Value, code_map: &CodeMap, offset: usize, ) -> Result<Self, Self::Error>
Tries to convert the given JSON value into Self, using the given
code_map and the offset of value in the code map.
Note to implementors: use the JsonArray::iter_mapped and
Object::iter_mapped methods to visit arrays and objects while
keeping track of the code map offset of each visited item.
Provided Methods§
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
