Expand description

Trait for creating value from a Value.

Typically each implementation can create a value from the specific type. For example, values of type bool or u32 are both represented by I32 and f64 values are represented by F64.

Required Methods§

Create a value of type Self from a given Value.

Returns None if the Value is of type different than expected by the conversion in question.

Implementations on Foreign Types§

This conversion assumes that boolean values are represented by I32 type.

This conversion assumes that u16 is represented as an I32.

This conversion assumes that u8 is represented as an I32.

This conversion assumes that i16 is represented as an I32.

This conversion assumes that i8 is represented as an I32.
