[−][src]Struct zenoh::PathExpr
A zenoh Path Expression used to express a selection of Path
s.
Similarly to a Path
, a Path is a set of strings separated by '/' , as in a filesystem path.
But unlike a Path
it can contain '*'
characters:
- a single
'*'
character matches any set of characters in a path, except'/'
. - while
"**"
matches any set of characters in a path, including'/'
.
A Path Expression can be absolute (i.e. starting with a '/'
) or relative to a Workspace
.
Implementations
impl PathExpr
[src]
pub fn new(p: String) -> ZResult<PathExpr>
[src]
Creates a new PathExpr from a String, checking its validity.
Returns Err(
ZError
)
if not valid.
pub fn as_str(&self) -> &str
[src]
Returns the Path as a &str.
pub fn is_relative(&self) -> bool
[src]
Returns true is this PathExpr is relative (i.e. not starting with '/'
).
pub fn is_a_path(&self) -> bool
[src]
Returns true is this PathExpr is a Path
(i.e. not containing any '*'
).
pub fn with_prefix(&self, prefix: &Path) -> Self
[src]
Returns the concatenation of prefix
with this PathExpr.
pub fn strip_prefix(&self, prefix: &Path) -> Option<Self>
[src]
If this PathExpr starts with prefix
returns a copy of this PathExpr with the prefix removed.
Otherwise, returns None
.
pub fn matches(&self, path: &Path) -> bool
[src]
Returns true if path
matches this PathExpr.
