Types

opts()

@type opts() :: [
  precision: 0..6,
  exactly: NaiveDateTime.t(),
  roughly: NaiveDateTime.t() | :now,
  epsilon: integer() | {integer(), integer()},
  before: NaiveDateTime.t() | :now,
  after: NaiveDateTime.t() | :now
]

Describes the arguments that can be passed to this matcher

t()

@opaque t()

Describes an instance of this matcher

Functions

naive_datetime(opts \\ [])

@spec naive_datetime(opts()) :: t()

Matches against NaiveDateTime values

Takes the following arguments:

  • precision: Requires the matched NaiveDateTime to have the specified microsecond precision
  • exactly: Requires the matched NaiveDateTime to be exactly equal to the specified NaiveDateTime
  • roughly: Requires the matched NaiveDateTime to be within epsilon seconds of the specified NaiveDateTime. The atom :now can be used to use the current time as the specified NaiveDateTime
  • epsilon: The bound(s) to use when determining how close (in microseconds) the matched NaiveDateTime time needs to be to roughly. Can be specified as a single integer that is used for both lower and upper bounds, or a tuple consisting of distinct lower and upper bounds. If not specified, defaults to 10_000_000 microseconds (10 seconds)
  • before: Requires the matched NaiveDateTime to be before or equal to the specified NaiveDateTime. The atom :now can be used to use the current time as the specified NaiveDateTime
  • after: Requires the matched NaiveDateTime to be after or equal to the specified NaiveDateTime. The atom :now can be used to use the current time as the specified NaiveDateTime
