Trait TryFromValueCoerce 

pub trait TryFromValueCoerce: Sized {
    // Required method
    fn try_from_value_coerce(value: &Value) -> Result<Self, FromValueError>;

    // Provided method
    fn from_value_coerce(value: &Value) -> Option<Self> { ... }
}

Trait for widening extraction of Rust types from Value.

Unlike TryFromValue, this allows compatible type conversions:

• i64 can be extracted from Int1, Int2, Int4, or Int8
• u64 can be extracted from Uint1, Uint2, Uint4, or Uint8
• f64 can be extracted from Float4, Float8, or any integer type

Required Methods

fn try_from_value_coerce(value: &Value) -> Result<Self, FromValueError>

Attempt to extract with widening conversion.

Provided Methods

fn from_value_coerce(value: &Value) -> Option<Self>

Extract with coercion, returning None for Undefined or incompatible types.

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.
