Configuration serialisation formats
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
None
Not specified: guess from the path

Error: unable to guess format
Implementations§
source§impl Format
impl Format
sourcepub fn guess_from_path(path: &Path) -> Format
pub fn guess_from_path(path: &Path) -> Format
Guess format from the path name
This does not open the file.
Potentially fallible: on error, returns Format::Unknown
.
This may be due to unrecognised file extension or due to the required
feature not being enabled.
