Trait to convert many dynamic path segment strings to a concrete value.
This is the
.. analog to
FromParam, and its functionality is identical
to it with one exception: this trait applies to segment parameters of the
param is of some type
T that implements
T::from_segments is called to convert the matched segments
Segments iterator) into the implementing type.
PathBuf implementation constructs a path from the segments iterator.
Each segment is percent-decoded. If a segment equals “..” before or after
decoding, the previous segment (if any) is omitted. For security purposes,
any other segments that begin with “*” or “.” are ignored. If a
percent-decoded segment results in invalid UTF8, an
Err is returned with

impl FromSegments<'_> for PathBuf[src]
PathBuf from a
Segments iterator. The returned
percent-decoded. If a segment is equal to “..”, the previous segment (if
any) is skipped.
For security purposes, if a segment meets any of the following conditions,
Err is returned indicating the condition met:
- Decoded segment starts with any of:
- Decoded segment ends with any of:
- Decoded segment contains any of:
- On Windows, decoded segment contains any of:
- Percent-encoding results in invalid UTF8.
As a result of these conditions, a
