Trait ConversionResultExt 

pub trait ConversionResultExt<T> {
    // Required methods
    fn context(self, field: impl Into<String>) -> Result<T, ConversionError>;
    fn with_context<F, S>(self, field: F) -> Result<T, ConversionError>
       where F: FnOnce() -> S,
             S: Into<String>;
}

Required Methods

fn context(self, field: impl Into<String>) -> Result<T, ConversionError>

Adds a field path segment if the result is an error.

fn with_context<F, S>(self, field: F) -> Result<T, ConversionError>

where F: FnOnce() -> S, S: Into<String>,

Computes and adds a field path segment only if the result is an error.

Dyn Compatibility

This trait is not dyn compatible.

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