Struct Property 

pub struct Property { /* private fields */ }

Represents a key-value property.

Properties are used to add context to telemetry events. Both key and value are stored as Arc<String> for efficient sharing.

Implementations

impl Property

pub fn new(key: Arc<String>, value: Arc<String>) -> Property

Creates a new Property.

pub fn key_str(&self) -> &str

Returns the key of the property as a string slice.

pub fn value_str(&self) -> &str

Returns the value of the property as a string slice.

Trait Implementations

impl Debug for Property

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

Formats the value using the given formatter.

impl Decode<'_, Postgres> for Property

fn decode( value: PgValueRef<'_>, ) -> Result<Property, Box<dyn Error + Send + Sync>>

Decode a new value of this type using a raw value from the database.

impl Encode<'_, Postgres> for Property

fn encode_by_ref( &self, buf: &mut PgArgumentBuffer, ) -> Result<IsNull, Box<dyn Error + Send + Sync>>

Writes the value of self into buf without moving self.

fn size_hint(&self) -> usize

fn encode( self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> Result<IsNull, Box<dyn Error + Send + Sync>>

where Self: Sized,

Writes the value of self into buf in the expected format for the database.

fn produces(&self) -> Option<<DB as Database>::TypeInfo>

impl PgHasArrayType for Property

fn array_type_info() -> PgTypeInfo

fn array_compatible(ty: &PgTypeInfo) -> bool

impl Type<Postgres> for Property

fn type_info() -> PgTypeInfo

Returns the canonical SQL type for this Rust type.

fn compatible(ty: &<DB as Database>::TypeInfo) -> bool

Determines if this Rust type is compatible with the given SQL type.
