Struct diesel::pg::PgMetadataCacheKey

pub struct PgMetadataCacheKey<'a> { /* private fields */ }

Available on crate features postgres_backend and i-implement-a-third-party-backend-and-opt-into-breaking-changes only.

The key used to lookup cached type oid’s inside of a PgMetadataCache.

Implementations

impl<'a> PgMetadataCacheKey<'a>

pub fn new(schema: Option<Cow<'a, str>>, type_name: Cow<'a, str>) -> Self

Construct a new cache key from an optional schema name and a type name

pub fn into_owned(self) -> PgMetadataCacheKey<'static>

Convert the possibly borrowed version of this metadata cache key into a lifetime independ owned version

Trait Implementations

impl<'a> Clone for PgMetadataCacheKey<'a>

fn clone(&self) -> PgMetadataCacheKey<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for PgMetadataCacheKey<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for PgMetadataCacheKey<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> PartialEq<PgMetadataCacheKey<'a>> for PgMetadataCacheKey<'a>

fn eq(&self, other: &PgMetadataCacheKey<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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