# [−][src]Trait approx::RelativeEq

    pub trait RelativeEq<Rhs = Self>: AbsDiffEq<Rhs> where
        Rhs: ?Sized, {
        fn default_max_relative() -> Self::Epsilon;
        fn relative_eq(
            &self,
            other: &Rhs,
            epsilon: Self::Epsilon,
            max_relative: Self::Epsilon
        ) -> bool;

        fn relative_ne(
            &self,
            other: &Rhs,
            epsilon: Self::Epsilon,
            max_relative: Self::Epsilon
        ) -> bool { ... }
    }

Equality comparisons between two numbers using both the absolute difference and relative based comparisons.

## Required methods

### `fn default_max_relative() -> Self::Epsilon`

The default relative tolerance for testing values that are far-apart.

This is used when no `max_relative` value is supplied to the `relative_eq` macro.

### `fn relative_eq(
&self,
other: &Rhs,
epsilon: Self::Epsilon,
max_relative: Self::Epsilon
) -> bool`

A test for equality that uses a relative comparison if the values are far apart.

### `fn relative_ne(
&self,
other: &Rhs,
epsilon: Self::Epsilon,
max_relative: Self::Epsilon
) -> bool`

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
