Struct TracePrefix

pub struct TracePrefix { /* private fields */ }

One hop in a token’s trace, which consists of the port and channel IDs of the sender

For example, given the token my_port-1/my_channel-1/my_port-2/my_channel-2/base_denom, my_port-1/my_channel-1 is a trace prefix, and my_port-2/my_channel-2 is another one. See TracePath which stitches trace prefixes together.

Implementations

impl TracePrefix

pub fn new(port_id: PortId, channel_id: ChannelId) -> TracePrefix

pub fn strip(s: &str) -> Option<(TracePrefix, Option<&str>)>

Returns a string slice with TracePrefix removed.

If the string starts with a TracePrefix, i.e. {port-id}/channel-{id}, it returns a tuple of the removed TracePrefix and the substring after the prefix.

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 start with a TracePrefix, this method returns None.

This method is analogous to strip_prefix from the standard library.
