Trait TryConvertFromRawReal 

pub trait TryConvertFromRawReal<RawRealIn: RawRealTrait>: RawRealTrait {
    // Required method
    fn try_convert_from_raw_real(
        value_in: RawRealIn,
        precision_out: u32,
    ) -> Result<Self, RawRealConversionError<RawRealIn, Self>>;
}

Conversion contract from one raw real type to another.

This trait is the low-level engine behind RawRealTrait::try_convert. Implementors define how to convert from RawRealIn into Self, including precision handling and exact representability guarantees.

Design

• RawRealIn is the input raw real type.
• Self is the output raw real type.
• precision_out is always interpreted by the output type (Self).

Error Semantics

Implementations should map failures to RawRealConversionError:

• input validation failures -> InputValidation
• output validation failures -> OutputValidation
• invalid requested precision for fixed-precision targets -> InvalidOutputPrecision
• exactness loss after conversion -> NonRepresentableExactly

Required Methods

fn try_convert_from_raw_real( value_in: RawRealIn, precision_out: u32, ) -> Result<Self, RawRealConversionError<RawRealIn, Self>>

Performs raw-real conversion with explicit output precision.

Parameters

• value_in: input raw value to be converted.
• precision_out: requested output precision interpreted by Self.

Returns

• Ok(Self) when conversion is valid and exact under the trait contract.
• Err(RawRealConversionError<RawRealIn, Self>) otherwise.

Dyn Compatibility

This trait is not dyn compatible.

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