Expand description
General utilities that may be useful while building Perseus apps.
Structs
Represents a duration that can be computed relative to the current time.
A simpler representation of a duration based on individual components.
An error type for invalid String
durations.
Functions
Same as cache_res
, but takes a function that returns a Result
, allowing
you to use ?
and the like inside your logic.
Runs the given function once and then caches the result to the filesystem for future execution. Think of this as filesystem-level memoizing. In future, this will be broken out into its own crate and wrapped by Perseus. The second parameter to this allows forcing the function to re-fetch data every time, which is useful if you want to revalidate data or test your fetching logic again. Note that a change to the logic will not trigger a reload unless you make it do so. For this reason, it’s recommended to only use this wrapper once you’ve tested your fetching logic.
Gets the path prefix to apply on the server. This uses the
PERSEUS_BASE_PATH
environment variable, which avoids hardcoding
something as changeable as this into the final binary. Hence however, that
variable must be the same as what’s set in <base>
(done automatically).
Trailing forward slashes will be trimmed automatically.
