Struct ScopedReservation 

pub struct ScopedReservation<'a> { /* private fields */ }

A temporary materialization charged until it is dropped or committed.

Implementations

impl ScopedReservation<'_>

pub fn with_storage<T, E: From<CodecError>>( &mut self, build: impl FnOnce() -> Result<T, E>, ) -> Result<T, E>

Account copied storage in this live temporary reservation.

pub fn with_storage_limit<T>( &mut self, build: impl FnOnce() -> Result<T, ResourceLimit>, ) -> Result<T, ResourceLimit>

Account temporary storage with a resource-only refusal channel.

pub fn grow_limit(&mut self, bytes: u64) -> Result<(), ResourceLimit>

Increases live temporary storage and returns the resource refusal.

pub fn grow(&mut self, bytes: u64) -> Result<(), CodecError>

Increases the live temporary reservation.

pub fn commit(self) -> Result<(), CodecError>

Converts the temporary reservation into session-retained bytes.

Trait Implementations

impl<'a> Debug for ScopedReservation<'a>

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

Formats the value using the given formatter.

impl Drop for ScopedReservation<'_>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
