Struct wasmtime_wasi::preview2::OccupiedEntry
source · pub struct OccupiedEntry<'a> { /* private fields */ }Expand description
Like std::collections::hash_map::OccupiedEntry, with a subset of
methods available in order to uphold Table invariants.
Implementations§
source§impl<'a> OccupiedEntry<'a>
impl<'a> OccupiedEntry<'a>
sourcepub fn get(&self) -> &(dyn Any + Send + Sync + 'static)
pub fn get(&self) -> &(dyn Any + Send + Sync + 'static)
Get the dynamically-typed reference to the resource.
sourcepub fn get_mut(&mut self) -> &mut (dyn Any + Send + Sync + 'static)
pub fn get_mut(&mut self) -> &mut (dyn Any + Send + Sync + 'static)
Get the dynamically-typed mutable reference to the resource.
sourcepub fn remove_entry(self) -> Result<Box<dyn Any + Send + Sync>, TableError>
pub fn remove_entry(self) -> Result<Box<dyn Any + Send + Sync>, TableError>
Remove the resource from the table, returning the contents of the
resource.
May fail with TableError::HasChildren if the entry has any
children, see Table::push_child.
If this method fails, the OccupiedEntry is consumed, but the
resource remains in the table.
