Struct Tolerance 

pub struct Tolerance { /* private fields */ }

What a destination is allowed to change, because its type system genuinely cannot represent the input.

Every allowance is a real, documented limitation of some destination — not a convenience. A pair that needs one is saying “this column cannot survive here”, which is worth stating explicitly in that pair’s test rather than hiding inside a loose comparison.

Implementations

impl Tolerance

pub fn exact() -> Self

No allowances: every value must land byte- and type-identical. Start here, and widen only with a comment naming the destination limitation.

pub fn skipping(self, column: &str) -> Self

Skip a column this destination cannot represent.

pub fn float_epsilon(self, eps: f64) -> Self

Compare floats within a relative epsilon.

pub fn empty_string_becomes_null(self) -> Self

Accept null where an empty string was sent.

pub fn lenient_scalar_kind(self) -> Self

Accept a scalar whose JSON kind changed but whose rendering did not.

Trait Implementations

impl Clone for Tolerance

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Tolerance

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Tolerance

fn default() -> Self

Returns the “default value” for a type.
