Struct node_testing::client::sc_executor::wasmi::TableRef [−]
pub struct TableRef(_);
Expand description
Reference to a table (See TableInstance
for details).
This reference has a reference-counting semantics.
Methods from Deref<Target = TableInstance>
pub fn initial_size(&self) -> u32
pub fn initial_size(&self) -> u32
Returns size this table was created with.
pub fn maximum_size(&self) -> Option<u32>
pub fn maximum_size(&self) -> Option<u32>
Returns maximum size TableInstance
can grow to.
pub fn current_size(&self) -> u32
pub fn current_size(&self) -> u32
Returns current size of the table.
Increases the size of the table by given number of elements.
Errors
Returns Err
if tried to allocate more elements than permited by limit.
Trait Implementations
type Target = TableInstance
type Target = TableInstance
The resulting type after dereferencing.
pub fn deref(&self) -> &TableInstance
pub fn deref(&self) -> &TableInstance

Should always be Self
The inverse inclusion map: attempts to construct self
from the equivalent element of its
superset. Read more
pub fn is_in_subset(&self) -> bool
pub fn is_in_subset(&self) -> bool
Checks if self
is actually part of its subset T
(and can be converted to it).
pub fn to_subset_unchecked(&self) -> SS
pub fn to_subset_unchecked(&self) -> SS
Use with care! Same as self.to_subset
but without any property checks. Always succeeds.
pub fn from_subset(element: &SS) -> SP
pub fn from_subset(element: &SS) -> SP
The inclusion map: converts self
to the equivalent element of its superset.
The counterpart to unchecked_from
.
Consume self to return an equivalent value of T
.
