Module mz_repr::adt::datetime

Date and time utilities.

Modules

• proto_date_time_units
  Nested message and enum types in ProtoDateTimeUnits.

Structs

• AnnotatedIntervalPart 🔒
  AnnotatedIntervalPart contains the tokens to be parsed, as well as the format to parse them.
• DateTimeFieldIterator
  An iterator over DateTimeFields
• DateTimeFieldValue
  Tracks a unit and a fraction from a parsed time-like string, e.g. INTERVAL ‘1.2’ DAYS.
• ParsedDateTime
  All of the fields that can appear in a literal DATE, TIME, TIMESTAMP or INTERVAL string.
• ProtoDateTimeUnits

Enums

• DateTimeField
• DateTimePart
  Order of definition is important for PartialOrd and Ord to be derived correctly
• DateTimeUnits
  Units of measurements associated with dates and times.
• TimePartFormat 🔒
  Interval strings can be presented in one of two formats:
• TimeStrToken 🔒
  TimeStrToken represents valid tokens in time-like strings, i.e those used in INTERVAL, TIMESTAMP/TZ, DATE, and TIME.

Constants

• _IMPL_ARBITRARY_FOR_DateTimeUnits 🔒

Functions

• determine_format_w_datetimefield 🔒
  Determines the format of the interval part (uses None to identify an indeterminant/ambiguous format). This is necessary because the interval string format is not LL(1); we instead parse as few tokens as possible to generate the string’s semantics.
• expected_dur_like_tokens 🔒
  Get the expected TimeStrTokens to parse SQL Standard time-like DateTimeFields, i.e. HOUR, MINUTE, SECOND. This is used for INTERVAL, TIMESTAMP, and TIME.
• expected_sql_standard_interval_tokens 🔒
  Get the expected TimeStrTokens to parse TimePartFormat::SqlStandard parts, starting from some DateTimeField. Delim tokens are never actually included in the output, but are illustrative of what the expected input of SQL Standard interval values looks like.
• fill_pdt_date 🔒
  Fills the year, month, and day fields of pdt using the TimeStrTokens in actual.
• fill_pdt_from_tokens 🔒
  Fills a ParsedDateTime’s fields using the actual tokens, starting at leading_field and descending to less significant DateTimeFields.
• fill_pdt_interval_pg 🔒
  Fills a ParsedDateTime’s fields for a single PostgreSQL-style interval parts, e.g. 1 month. Invoke this function once for each PostgreSQL-style interval part.
• fill_pdt_interval_sql 🔒
  Fills a ParsedDateTime’s fields when encountering SQL standard-style interval parts, e.g. 1-2 for Y-M 4:5:6.7 for H:M:S.NS.
• fill_pdt_time 🔒
  Fills the hour, minute, and second fields of pdt using the TimeStrTokens in actual.
• ltrim_delim_or_colon 🔒
  PostgreSQL treats out-of-place colons as errant punctuation marks, and trims them.
• split_timestamp_string 🔒
  Takes a ‘date timezone’ ‘date time timezone’ string and splits it into ‘date {time}’ and ‘timezone’ components
• tokenize_time_str 🔒
  Convert a string from a time-like datatype (INTERVAL, TIMESTAMP/TZ, DATE, and TIME) into Vec<TimeStrToken>.
• trim_and_return_sign 🔒
