Enum CasePolicy 

pub enum CasePolicy {
    Domain,
    All,
    Preserve,
}

How to handle letter case.

Variants

Domain

Lowercase domain only (RFC says local part is case-sensitive, but domain is not).

All

Lowercase both local part and domain. Most providers are case-insensitive.

Preserve

Preserve original case everywhere.

Trait Implementations

impl Clone for CasePolicy

fn clone(&self) -> CasePolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CasePolicy

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

Formats the value using the given formatter.

impl Default for CasePolicy

fn default() -> CasePolicy

Returns the “default value” for a type.

impl PartialEq for CasePolicy

fn eq(&self, other: &CasePolicy) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
