Struct near_sdk::collections::LookupSet [−][src]
pub struct LookupSet<T> { /* fields omitted */ }
Expand description
An non-iterable implementation of a set that stores its content directly on the trie.
Implementations
Create a new map. Use element_prefix
as a unique prefix for trie keys.
Inserts a serialized element into the set.
If the set did not have this value present, true
is returned.
If the set did have this value present, false
is returned.
Removes a value from the set. Returns whether the value was present in the set.
Adds a value to the set.
If the set did not have this value present, true
is returned.
If the set did have this value present, false
is returned.
Trait Implementations
Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes. Read more
Deserialize this instance from a slice of bytes.
Whether Self is u8.
NOTE: Vec<u8>
is the most common use-case for serialization and deserialization, it’s
worth handling it as a special case to improve performance.
It’s a workaround for specific Vec<u8>
implementation versus generic Vec<T>
implementation. See https://github.com/rust-lang/rfcs/pull/1210 for details. Read more
