Struct stam::DataKeyHandle

pub struct DataKeyHandle(/* private fields */);

Handle to an instance of DataKey in the store (AnnotationDataSet)

Trait Implementations

impl Clone for DataKeyHandle

fn clone(&self) -> DataKeyHandle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl DataSize for DataKeyHandle

const IS_DYNAMIC: bool = false

If true, the type has a heap size that can vary at runtime, depending on the actual value.

const STATIC_HEAP_SIZE: usize = 0usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

impl Debug for DataKeyHandle

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

Formats the value using the given formatter.

impl<'bytes, Ctx> Decode<'bytes, Ctx> for DataKeyHandle

fn decode( __d777: &mut Decoder<'bytes>, __ctx777: &mut Ctx ) -> Result<DataKeyHandle, Error>

Decode a value using the given Decoder.

fn nil() -> Option<Self>

If possible, return a nil value of Self.

impl<Ctx> Encode<Ctx> for DataKeyHandle

fn encode<__W777>( &self, __e777: &mut Encoder<__W777>, __ctx777: &mut Ctx ) -> Result<(), Error<__W777::Error>>

where __W777: Write,

Encode a value of this type using the given Encoder.

fn is_nil(&self) -> bool

Is this value of Self a nil value?

impl<'a> From<&DataKeyHandle> for BuildItem<'a, DataKey>

fn from(handle: &DataKeyHandle) -> Self

Converts to this type from the input type.

impl<'a> From<DataKeyHandle> for BuildItem<'a, DataKey>

fn from(handle: DataKeyHandle) -> Self

Converts to this type from the input type.

impl Handle for DataKeyHandle

fn new(intid: usize) -> Self

Create a new handle for an internal ID. You shouldn’t need to use this as handles will always be generated for you by higher-level functions. In fact, creating them yourself like this should be considered dangerous!

fn as_usize(&self) -> usize

Returns the internal index for this handle.

fn reindex(&self, gaps: &[(Self, isize)]) -> Self

Low-level method to compute a new handle based on a list of gaps, used by reindexers. There is usually no reason to call this yourself.

impl Hash for DataKeyHandle

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 Ord for DataKeyHandle

fn cmp(&self, other: &DataKeyHandle) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for DataKeyHandle

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

impl PartialOrd for DataKeyHandle

fn partial_cmp(&self, other: &DataKeyHandle) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'a> Request<DataKey> for DataKeyHandle

fn to_handle<'store, S>(&self, _store: &'store S) -> Option<DataKeyHandle>

where S: StoreFor<DataKey>,

Returns the handle for this item, looking it up in the store

fn requested_id(&self) -> Option<&str>

If this type encapsulates an Id, this returns it (borrowed)

fn requested_id_owned(self) -> Option<String>

If this type encapsulates an Id, this returns it (oened)

fn requested_handle(&self) -> Option<T::HandleType>

If this type encapsulates a handle, this returns it

fn any(&self) -> bool

Represents a request for any value in certain contexts
