Column metadata

Implementations

source

impl ColumnMeta

source

pub fn field_iter(&mut self) -> FieldIteratorⓘNotable traits for FieldIterator`impl Iterator for FieldIterator type Item = Field;`

returns an iterator over the fields of this column

source

pub fn name(&self) -> String

Gets the name of the column.

source

pub fn get_type(&self) -> _CassColumnType

Gets the type of the column.

source

pub fn data_type(&self) -> ConstDataType

Gets the data type of the column.

source

pub fn field_by_name(&self, name: &str) -> Option<Value>

Gets a metadata field for the provided name. Metadata fields allow direct access to the column data found in the underlying “columns” metadata table.
