Struct NamedDataType 

pub struct NamedDataType { /* private fields */ }

A named data type.

Implementations

impl NamedDataType

pub fn new(name: String, data_type: DataType) -> Self

Create a new NamedDataType.

pub fn name(&self) -> &str

The name of the data type.

pub const fn data_type(&self) -> &DataType

The underlying data type extension.

pub fn fill_value_from_metadata( &self, fill_value: &FillValueMetadataV3, ) -> Result<FillValue, DataTypeFillValueMetadataError>

Create a fill value from metadata.

Errors

Returns DataTypeFillValueMetadataError if the fill value is incompatible with the data type.

Methods from Deref<Target = DataType>

pub fn name(&self) -> String

Returns the name.

pub fn metadata(&self) -> MetadataV3

Returns the metadata.

pub fn size(&self) -> DataTypeSize

Returns the DataTypeSize.

pub fn fixed_size(&self) -> Option<usize>

Returns the size in bytes of a fixed-size data type, otherwise returns None.

pub fn is_fixed(&self) -> bool

Returns true if the data type has a fixed size.

pub fn is_variable(&self) -> bool

Returns true if the data type has a variable size.

pub fn fill_value_from_metadata( &self, fill_value: &FillValueMetadataV3, ) -> Result<FillValue, DataTypeFillValueMetadataError>

Create a fill value from metadata.

Errors

Returns DataTypeFillValueMetadataError if the fill value is incompatible with the data type.

pub fn metadata_fill_value( &self, fill_value: &FillValue, ) -> Result<FillValueMetadataV3, DataTypeFillValueError>

Create fill value metadata.

Errors

Returns an DataTypeFillValueError if the metadata cannot be created from the fill value.
