Implementations

impl<'a> Parameter<'a>

pub async fn get(&self, pool: &PgPool) -> Result<Option<Value>, Error>

Get the current Value for this parameter.

If you want the full/raw Setting, use Setting::get instead.

pub async fn set<V: Into<Value>>( &self, pool: &PgPool, value: V ) -> Result<(), Error>

Set the current value for this parameter.

pub async fn reset(&self, pool: &PgPool) -> Result<(), Error>

Reset the value for this parameter.

Trait Implementations

impl<'a> AsRef<str> for Parameter<'a>

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl<'a> Clone for Parameter<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Parameter<'a>

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

Formats the value using the given formatter.

impl<'a> Display for Parameter<'a>

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

Formats the value using the given formatter.

impl<'a> From<&'a Setting> for Parameter<'a>

fn from(setting: &'a Setting) -> Self

Converts to this type from the input type.

impl<'a> From<&'a str> for Parameter<'a>

fn from(name: &'a str) -> Self

Converts to this type from the input type.

impl<'a> Hash for Parameter<'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 for Parameter<'a>

fn eq(&self, other: &Parameter<'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.
