Struct TracePath

pub struct TracePath(/* private fields */);

A full trace path modelled as a collection of TracePrefixs.

Internally, the TracePath is modelled as a Vec<TracePrefix> but with the order reversed, i.e. “transfer/channel-0/transfer/channel-1/uatom” => ["transfer/channel-1", "transfer/channel-0"] This is done for ease of addition/removal of prefixes.

Implementations

impl TracePath

pub fn starts_with(&self, prefix: &TracePrefix) -> bool

Returns true iff this path starts with the specified prefix

pub fn remove_prefix(&mut self, prefix: &TracePrefix)

Removes the specified prefix from the path if there is a match, otherwise does nothing.

pub fn add_prefix(&mut self, prefix: TracePrefix)

Adds the specified prefix to the path.

pub fn is_empty(&self) -> bool

Returns true if the path is empty and false otherwise.

pub fn empty() -> TracePath

Return empty trace path

pub fn trim(s: &str) -> (TracePath, Option<&str>)

Returns a string slice with TracePath or all TracePrefixes repeatedly removed.

If the string starts with a TracePath, it returns a tuple of the removed TracePath and the substring after the TracePath.

If the substring is empty, it returns None. Otherwise, the substring starts with /. In that case, the leading / is stripped and returned.

If the string does not contain any TracePrefix, it returns the original string.

This method is analogous to trim_start_matches from the standard library.
