pub struct FastFieldReaders { /* private fields */ }

Expand description

Provides access to all of the BitpackedFastFieldReader.

Internally, FastFieldReaders have preloaded fast field readers, and just wraps several HashMap.

Implementations

source

impl FastFieldReaders

source

pub fn u64(&self, field: Field) -> Result<DynamicFastFieldReader<u64>>

Returns the u64 fast field reader reader associated to field.

If field is not a u64 fast field, this method returns an Error.

source

pub fn u64_lenient(&self, field: Field) -> Result<DynamicFastFieldReader<u64>>

Returns the u64 fast field reader reader associated to field, regardless of whether the given field is effectively of type u64 or not.

If not, the fastfield reader will returns the u64-value associated to the original FastValue.

source

pub fn i64(&self, field: Field) -> Result<DynamicFastFieldReader<i64>>

Returns the i64 fast field reader reader associated to field.

If field is not a i64 fast field, this method returns an Error.

source

pub fn date(&self, field: Field) -> Result<DynamicFastFieldReader<DateTime>>

Returns the date fast field reader reader associated to field.

If field is not a date fast field, this method returns an Error.

source

pub fn f64(&self, field: Field) -> Result<DynamicFastFieldReader<f64>>

Returns the f64 fast field reader reader associated to field.

If field is not a f64 fast field, this method returns an Error.

source

pub fn u64s(&self, field: Field) -> Result<MultiValuedFastFieldReader<u64>>

Returns a u64s multi-valued fast field reader reader associated to field.

If field is not a u64 multi-valued fast field, this method returns an Error.

source

pub fn u64s_lenient(
&self,
field: Field
) -> Result<MultiValuedFastFieldReader<u64>>

Returns a u64s multi-valued fast field reader reader associated to field, regardless of whether the given field is effectively of type u64 or not.

If field is not a u64 multi-valued fast field, this method returns an Error.

source

pub fn i64s(&self, field: Field) -> Result<MultiValuedFastFieldReader<i64>>

Returns a i64s multi-valued fast field reader reader associated to field.

If field is not a i64 multi-valued fast field, this method returns an Error.

source

pub fn f64s(&self, field: Field) -> Result<MultiValuedFastFieldReader<f64>>

Returns a f64s multi-valued fast field reader reader associated to field.

If field is not a f64 multi-valued fast field, this method returns an Error.

source

pub fn dates(
&self,
field: Field
) -> Result<MultiValuedFastFieldReader<DateTime>>

Returns a time::OffsetDateTime multi-valued fast field reader reader associated to field.

If field is not a time::OffsetDateTime multi-valued fast field, this method returns an Error.

source

pub fn bytes(&self, field: Field) -> Result<BytesFastFieldReader>

Returns the bytes fast field reader associated to field.

If field is not a bytes fast field, returns an Error.
