pub fn set(&mut self, name: impl IntoGStr, value: impl Into<Value> + Send)

Sets field name to the given value value.

Overrides any default or previously defined value for name.

pub fn set_if( &mut self, name: impl IntoGStr, value: impl Into<Value> + Send, predicate: bool, )

Sets field name to the given inner value if value is Some.

This has no effect if the predicate evaluates to false, i.e. default or previous value for name is kept.

pub fn set_if_some( &mut self, name: impl IntoGStr, value: Option<impl Into<Value> + Send>, )

Sets field name to the given inner value if value is Some.

This has no effect if the value is None, i.e. default or previous value for name is kept.

pub fn set_from_iter<V: ValueType + Into<Value> + FromIterator<SendValue> + Send>( &mut self, name: impl IntoGStr, iter: impl IntoIterator<Item = impl ToSendValue>, )

Sets field name using the given ValueType V built from iter’s the Items.

Overrides any default or previously defined value for name.

pub fn set_if_not_empty<V: ValueType + Into<Value> + FromIterator<SendValue> + Send>( &mut self, name: impl IntoGStr, iter: impl IntoIterator<Item = impl ToSendValue>, )

Sets field name using the given ValueType V built from iter’s Items, if iter` is not empty.

This has no effect if iter is empty, i.e. previous value for name is unchanged.

pub fn set_value(&mut self, name: impl IntoGStr, value: SendValue)

Sets field name to the given value value.

Overrides any default or previously defined value for name.

pub fn set_value_if( &mut self, name: impl IntoGStr, value: SendValue, predicate: bool, )

Sets field name to the given inner value if value is Some.

This has no effect if the predicate evaluates to false, i.e. default or previous value for name is kept.

pub fn set_value_if_some( &mut self, name: impl IntoGStr, value: Option<SendValue>, )

Sets field name to the given inner value if value is Some.

This has no effect if the value is None, i.e. default or previous value for name is kept.

Trait Implementations

impl AsMut<BufferPoolConfigRef> for BufferPoolConfig

fn as_mut(&mut self) -> &mut BufferPoolConfigRef

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

impl AsRef<BufferPoolConfigRef> for BufferPoolConfig

fn as_ref(&self) -> &BufferPoolConfigRef

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

impl Clone for BufferPoolConfig

fn clone(&self) -> BufferPoolConfig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BufferPoolConfig

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

Formats the value using the given formatter.

impl Deref for BufferPoolConfig

type Target = BufferPoolConfigRef

The resulting type after dereferencing.

fn deref(&self) -> &BufferPoolConfigRef

Dereferences the value.

impl DerefMut for BufferPoolConfig

fn deref_mut(&mut self) -> &mut BufferPoolConfigRef

Mutably dereferences the value.

impl PartialEq for BufferPoolConfig

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