Struct sval_buffer::Value

pub struct Value<'sval> { /* private fields */ }

An immutable buffered value.

This type is more compact than ValueBuf.

Implementations

impl<'sval> Value<'sval>

pub fn collect(v: &'sval impl Value + ?Sized) -> Result<Self, Error>

Buffer a value.

This method will fail if the alloc feature is not enabled.

pub fn into_owned(self) -> Result<Value<'static>, Error>

Fully buffer this value, including any internal borrowed data.

This method will fail if the alloc feature is not enabled.

impl Value<'static>

pub fn collect_owned(v: impl Value) -> Result<Self, Error>

Fully buffer a value, including any internal borrowed data.

This method will fail if the alloc feature is not enabled.
