Module mz_repr::row

Modules

• 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.

Enums

• ProtoDatumOther
• Tag 🔒

Constants

• LONG 🔒
• SHORT 🔒
• TINY 🔒

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 🔒
