Trait Implementations

impl BindRustType<Map> for Statement

fn bind(&mut self, index: usize, value: Map) -> Result<&mut Self>

binds a rust type to C* by index

fn bind_by_name(&mut self, col: &str, value: Map) -> Result<&mut Self>

impl CassCollection for Map

fn data_type(&self) -> ConstDataType<'_>

Gets the data type of a collection.

fn append_int8(&mut self, value: i8) -> Result<&mut Self>

Appends a “tinyint” to the collection.

fn append_int16(&mut self, value: i16) -> Result<&mut Self>

Appends an “smallint” to the collection.

fn append_int32(&mut self, value: i32) -> Result<&mut Self>

Appends an “int” to the collection.

fn append_uint32(&mut self, value: u32) -> Result<&mut Self>

Appends a “date” to the collection.

fn append_int64(&mut self, value: i64) -> Result<&mut Self>

Appends a “bigint”, “counter”, “timestamp” or “time” to the collection.

fn append_float(&mut self, value: f32) -> Result<&mut Self>

Appends a “float” to the collection.

fn append_double(&mut self, value: f64) -> Result<&mut Self>

Appends a “double” to the collection.

fn append_bool(&mut self, value: bool) -> Result<&mut Self>

Appends a “boolean” to the collection.

fn append_string(&mut self, value: &str) -> Result<&mut Self>

Appends an “ascii”, “text” or “varchar” to the collection.

fn append_bytes(&mut self, value: Vec<u8>) -> Result<&mut Self>

Appends a “blob”, “varint” or “custom” to the collection.

fn append_uuid(&mut self, value: Uuid) -> Result<&mut Self>

Appends a “uuid” or “timeuuid” to the collection.

fn append_inet(&mut self, value: Inet) -> Result<&mut Self>

Appends an “inet” to the collection.

fn append_list(&mut self, value: List) -> Result<&mut Self>

Appends a “list” to the collection.

fn append_set(&mut self, value: Set) -> Result<&mut Self>

Appends a “set” to the collection.

fn append_map(&mut self, value: Map) -> Result<&mut Self>

Appends a “map” to the collection.

fn append_tuple(&mut self, value: Tuple) -> Result<&mut Self>

Appends a “tuple” to the collection.

fn append_user_type(&mut self, value: &UserType) -> Result<&mut Self>

Appends a “udt” to the collection.

type Value = CassCollection_

The type of value held by this collection

fn with_capacity(capacity: usize) -> Self

Creates a new collection, specifying a capacity which will be used as a size hint to avoid re-allocations of the collection internally.

fn new_from_data_type(value: DataType, item_count: usize) -> Self

Creates a new collection from an existing data type.

fn new() -> Self

Creates a new collection.

impl Debug for Map

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

Formats the value using the given formatter.

impl Drop for Map

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.

impl Send for Map
