Enum Collation 

pub enum Collation {
    C,
    Utf8,
    Custom(String),
}

PostgreSQL collation specifications

Supports common collations and custom names. When used, generates: field COLLATE "collation_name"

Variants

C

Binary collation (fast, deterministic)

Utf8

UTF-8 binary collation

Custom(String)

Implementations

impl Collation

pub fn as_str(&self) -> &str

Get the PostgreSQL collation name as a string

Trait Implementations

impl Clone for Collation

fn clone(&self) -> Collation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Collation

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

Formats the value using the given formatter.

impl Display for Collation

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

Formats the value using the given formatter.

impl PartialEq for Collation

fn eq(&self, other: &Collation) -> 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.
