Trait TryConvert 

pub trait TryConvert: Sized {
    // Required method
    fn try_convert(val: Value) -> Result<Self, Error>;
}

Conversions from Value to Rust types.

Required Methods

fn try_convert(val: Value) -> Result<Self, Error>

Convert val into Self.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
