Struct Props 

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

A list of key-value pairs that associate arbitrary properties with an object. Keys are null-terminated strings and values are arbitrary binary blobs, although by convention both are usually null-terminated ASCII strings.

Implementations

impl Props

pub fn new() -> Self

Creates a new, empty property list.

pub fn set<T>(&mut self, prop: Prop, value: T)

where T: AsRef<CStr>,

Sets a well-known property in the map.

If the property already has a value, it will be overwritten with the new one.

pub fn set_bytes<K, V>(&mut self, key: K, value: V)

where K: AsRef<CStr>, V: AsRef<[u8]>,

Sets a a property in the map.

If the property already has a value, it will be overwritten with the new one.

pub fn get(&self, prop: Prop) -> Option<&[u8]>

Gets the value of a well-known property.

If prop is not in the map, returns None.

pub fn get_mut(&mut self, prop: Prop) -> Option<&mut [u8]>

Gets the value of a well-known property.

If prop is not in the map, returns None.

pub fn get_bytes<K>(&self, key: K) -> Option<&[u8]>

where K: AsRef<CStr>,

Gets a property from the map.

pub fn get_bytes_mut<K>(&mut self, key: K) -> Option<&mut [u8]>

where K: AsRef<CStr>,

s Get a property from the map.

pub fn iter(&self) -> Iter<'_, Box<CStr>, Box<[u8]>>

Create an Iterator over the properties.

Trait Implementations

impl Clone for Props

fn clone(&self) -> Props

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Props

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

Formats the value using the given formatter.

impl Default for Props

fn default() -> Props

Returns the “default value” for a type.

impl PartialEq for Props

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

impl TagStructRead for Props

fn read( ts: &mut TagStructReader<'_>, _protocol_version: u16, ) -> Result<Self, ProtocolError>

Read an instance of Self from a tagstruct.

impl TagStructWrite for Props

fn write( &self, w: &mut TagStructWriter<'_>, _protocol_version: u16, ) -> Result<(), ProtocolError>

Write self into a tagstruct.

impl Eq for Props

impl StructuralPartialEq for Props
