Implementations

impl SamplingContent

pub fn text(text: impl Into<String>) -> SamplingContent

Create text content.

pub fn as_text(&self) -> Option<&str>

Get the text if this is text content.

Trait Implementations

impl Clone for SamplingContent

fn clone(&self) -> SamplingContent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SamplingContent

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

Formats the value using the given formatter.

impl Default for SamplingContent

fn default() -> SamplingContent

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SamplingContent

fn deserialize<__D>( __deserializer: __D, ) -> Result<SamplingContent, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<SamplingContent> for SamplingContentBlock

fn from(c: SamplingContent) -> SamplingContentBlock

Converts to this type from the input type.

impl PartialEq for SamplingContent

fn eq(&self, other: &SamplingContent) -> 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 Serialize for SamplingContent

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
