Trait ConvUtil

pub trait ConvUtil {
    // Provided methods
    fn approx_as<Dst>(self) -> Result<Dst, Self::Err>
       where Self: Sized + ApproxInto<Dst> { ... }
    fn approx_as_by<Dst, Scheme>(self) -> Result<Dst, Self::Err>
       where Self: Sized + ApproxInto<Dst, Scheme>,
             Scheme: ApproxScheme { ... }
    fn into_as<Dst>(self) -> Dst
       where Self: Sized + Into<Dst> { ... }
    fn try_as<Dst>(self) -> Result<Dst, Self::Err>
       where Self: Sized + TryInto<Dst> { ... }
    fn value_as<Dst>(self) -> Result<Dst, Self::Err>
       where Self: Sized + ValueInto<Dst> { ... }
}

This extension trait exists to simplify using various conversions.

If there is more than one implementation for a given type/trait pair, a simple call to *_into may not be uniquely resolvable. Due to the position of the type parameter (on the trait itself), it is cumbersome to specify the destination type. A similar problem exists for approximation schemes.

See also the ConvAsUtil trait.

Note: There appears to be a bug in rustdoc’s output. This trait is implemented for all types, though the methods are only available for types where the appropriate conversions are defined.

Provided Methods

fn approx_as<Dst>(self) -> Result<Dst, Self::Err>

where Self: Sized + ApproxInto<Dst>,

Approximate the subject to a given type with the default scheme.

fn approx_as_by<Dst, Scheme>(self) -> Result<Dst, Self::Err>

where Self: Sized + ApproxInto<Dst, Scheme>, Scheme: ApproxScheme,

Approximate the subject to a given type with a specific scheme.

fn into_as<Dst>(self) -> Dst

where Self: Sized + Into<Dst>,

Convert the subject to a given type.

fn try_as<Dst>(self) -> Result<Dst, Self::Err>

where Self: Sized + TryInto<Dst>,

Attempt to convert the subject to a given type.

fn value_as<Dst>(self) -> Result<Dst, Self::Err>

where Self: Sized + ValueInto<Dst>,

Attempt a value conversion of the subject to a given type.
