Modules

columnar 🔒

columnation 🔒

encode 🔒

A permanent storage encoding for rows.

iter

Defines a “lending iterator” for Row

proto_datum

Nested message and enum types in ProtoDatum.

Structs

DatumDictIter

DatumList

A sequence of Datums

DatumListIter

DatumMap

A mapping from string keys to Datums

DatumNested

Represents a single Datum, appropriate to be nested inside other Datums.

ProtoArray

ProtoArrayDimension

ProtoDatum

ProtoDict

ProtoDictElement

ProtoNumeric

See [dec::to_packed_bcd] and http://speleotrove.com/decimal/dnpack.html for more information on this format.

ProtoRange

ProtoRangeInner

ProtoRow

Row

A packed representation for Datums.

RowArena

RowArena is used to hold on to temporary Rows for functions like eval that need to create complex Datums but don’t have a Row to put them in yet.

RowPacker

Packs datums into a Row.

RowRef

A contiguous slice of bytes that are row data.

SharedRow

A thread-local row, which can be borrowed and returned.

Functions

checked_timestamp_nanos 🔒

Returns an i64 representing a NaiveDateTime, if said i64 can be round-tripped back to a NaiveDateTime.

date_to_array 🔒

datum_list_size

Number of bytes required by a list of datums. This computes the size that would be required if the given datums were packed into a list.

datum_size

Number of bytes required by the datum. This is used to optimistically pre-allocate buffers for packing rows.

datums_size

Number of bytes required by a sequence of datums.

min_bytes_signed 🔒

min_bytes_unsigned 🔒

naive_date_to_arrays 🔒

push_date 🔒

push_datum 🔒

push_lengthed_bytes 🔒

push_naive_date 🔒

push_time 🔒

push_untagged_bytes 🔒

read_byte 🔒

read_byte_array 🔒

read_byte_array_extending_negative 🔒

Read length bytes from data at offset, updating the latter. Extend the resulting buffer to a negative N-byte twos complement integer by filling the remaining bits with 1.

read_byte_array_extending_nonnegative 🔒

Read length bytes from data at offset, updating the latter. Extend the resulting buffer to a positive or zero N-byte twos complement integer by filling the remaining bits with 0.

read_byte_array_sign_extending 🔒

Read length bytes from data at offset, updating the latter. Extend the resulting buffer to an array of N bytes by inserting FILL in the k most significant bytes, where k = N - length.

read_date 🔒

read_datum^⚠

Read a datum starting at byte offset.

read_lengthed_datum 🔒 ^⚠

Read a data whose length is encoded in the row before its contents.

read_naive_date 🔒

read_time 🔒

read_untagged_bytes 🔒

Read a byte slice starting at byte offset.

row_size

Return the number of bytes these Datums would use if packed as a Row.

time_to_arrays 🔒
