}Expand description
A generic trait for converting a value to a number. Adapted from num_traits::ToPrimitive to support bool.
A value can be represented by the target type when it lies within
the range of scalars supported by the target type.
For example, a negative integer cannot be represented by an unsigned
integer type, and an i64 with a very high magnitude might not be
convertible to an i32.
On the other hand, conversions with possible precision loss or truncation
are admitted, like an f32 with a decimal part to an integer type, or
even a large f64 saturating to f32 infinity.
The methods panic when the value cannot be represented by the target type.
Required Methods§
Provided Methods§
Sourcefn to_i128(&self) -> i128
fn to_i128(&self) -> i128
Converts the value of self to an i128.
The default implementation converts through to_i64(). Types implementing
this trait should override this method if they can represent a greater range.
Sourcefn to_u128(&self) -> u128
fn to_u128(&self) -> u128
Converts the value of self to a u128.
The default implementation converts through to_u64(). Types implementing
this trait should override this method if they can represent a greater range.
Sourcefn to_f16(&self) -> f16
fn to_f16(&self) -> f16
Converts the value of self to an f16. Overflows may map to positive
or negative infinity.
Sourcefn to_bf16(&self) -> bf16
fn to_bf16(&self) -> bf16
Converts the value of self to an bf16. Overflows may map to positive
or negative infinity.
Sourcefn to_f32(&self) -> f32
fn to_f32(&self) -> f32
Converts the value of self to an f32. Overflows may map to positive
or negative infinity.
Sourcefn to_f64(&self) -> f64
fn to_f64(&self) -> f64
Converts the value of self to an f64. Overflows may map to positive
or negative infinity.
The default implementation tries to convert through to_i64(), and
failing that through to_u64(). Types implementing this trait should
override this method if they can represent a greater range.
Sourcefn to_bool(&self) -> bool
fn to_bool(&self) -> bool
Converts the value of self to a bool.
Rust only considers 0 and 1 to be valid booleans, but for compatibility, C semantics are
adopted (anything that’s not 0 is true).
The default implementation tries to convert through to_i64(), and
failing that through to_u64(). Types implementing this trait should
override this method if they can represent a greater range.
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
