Trait PolarsContext 

pub trait PolarsContext<T> {
    // Required methods
    fn context(self, ctx: &'static str) -> Result<T, PolarsError>;
    fn with_context<F>(self, f: F) -> Result<T, PolarsError>
       where F: FnOnce() -> String;
}

Required Methods

fn context(self, ctx: &'static str) -> Result<T, PolarsError>

fn with_context<F>(self, f: F) -> Result<T, PolarsError>

where F: FnOnce() -> String,

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.
