Module datetime

Timestamp parsing and utilities to translate to and from the chrono and time crates.

Modules

chrono

Utilies to convert back and forth between chrono’s data structures and the hl7-parser ones All implementations here are implemented as TryFrom and From traits between the TimeStamp struct and various chrono types. This allows for easy conversion between the two types. The TryFrom implementations will return an error if the conversion is not possible, such as if the date or time components are invalid. The From implementations will always succeed and will set missing components to zero or the epoch if necessary.

jiff

Utilies to convert back and forth between jiff’s data structures and the hl7-parser ones All implementations here are implemented as TryFrom and From traits between the TimeStamp struct and various chrono types. This allows for easy conversion between the two types. The TryFrom implementations will return an error if the conversion is not possible, such as if the date or time components are invalid. The From implementations will always succeed and will set missing components to zero or the epoch if necessary.

time_crate

Utilies to convert back and forth between time’s data structures and the hl7-parser ones All implementations here are implemented as TryFrom and From traits between the TimeStamp struct and various time types. This allows for easy conversion between the two types. The TryFrom implementations will return an error if the conversion is not possible, such as if the date or time components are invalid. The From implementations will always succeed and will set missing components to zero or the epoch if necessary.

Structs

Date

A parsed date without a time component

Time

The results of parsing a timestamp. Note that the timestamp is not validated, i.e. it may not be a valid date or time.

TimeStamp

The results of parsing a timestamp. Note that the timestamp is not validated, i.e. it may not be a valid date or time.

TimeStampOffset

A parsed timezone offset in hours and minutes

Enums

DateTimeParseError

Errors that can result from parsing HL7 timestamps

ErroredDateTimeComponent

Traits

DateTime

Trait for parsing HL7 date and time strings into Date, Time, and TimeStamp structs

Functions

parse_date

Parse an HL7 date in the format: YYYY[MM[DD]

parse_time

Parse an HL7 time in the format: HH[MM[SS[.S[S[S[S]]]]]][+/-ZZZZ]

parse_timestamp

Parse an HL7 timestamp in the format: YYYY[MM[DD[HH[MM[SS[.S[S[S[S]]]]]]]]][+/-ZZZZ]
