Trait Validate

pub trait Validate {
    // Required methods
    fn has_shape(self, shape: (usize, usize)) -> Self;
    fn has_cols(self, columns: Vec<&str>) -> Self;
    fn has_length(self, length: Comparison) -> Self;
    fn validate<S>(self, expr: Expr) -> Self;
}

Required Methods

fn has_shape(self, shape: (usize, usize)) -> Self

Validate the shape of the dataframe

fn has_cols(self, columns: Vec<&str>) -> Self

Validate the columns of the dataframe

fn has_length(self, length: Comparison) -> Self

Validate the length of the dataframe

fn validate<S>(self, expr: Expr) -> Self

Validate the dataframe with an expression

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.
