Trait OptionExt 

pub trait OptionExt {
    type Item;

    // Required methods
    fn and_try<F, T>(self, f: F) -> TractResult<Option<T>>
       where F: Fn(Self::Item) -> TractResult<T>;
    fn and_ok<F, T>(self, f: F) -> TractResult<Option<T>>
       where F: Fn(Self::Item) -> T;

Required Methods

fn and_try<F, T>(self, f: F) -> TractResult<Option<T>>

where F: Fn(Self::Item) -> TractResult<T>,

fn and_ok<F, T>(self, f: F) -> TractResult<Option<T>>

where F: Fn(Self::Item) -> T,

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.
