Greetings,
I'm migrating some Python code to Rust, but I stuck at a dead end... Sorry to provide some .py lines over here, but I got some doubts about the best (fastest) way to do that in Rust.
Executing the function parsertoken("_My input.string", " _,.", 2)
will result "input".
Parsercount("Rust=-rocks!", " =-")
will result 2,
def parsertoken(istring, idelimiters, iposition):
"""
Return a specific token of a given input string,
considering its position and the provided delimiters
:param istring: raw input string
:param idelimiteres: delimiters to split the tokens
:param iposition: position of the token
:return: token
"""
vlist=''.join([s if s not in idelimiters else ' ' for s in istring]).split()
return vlist[vposition]
def parsercount(istring, idelimiters):
"""
Return the number of tokens at the input string
considering the delimiters provided
:param istring: raw input string
:param idelimiteres: delimiters to split the tokens
:return: a list with all the tokens found
"""
vlist=''.join([s if s not in idelimiters else ' ' for s in istring]).split()
return len(vlist)-1
Given I really care about speed, in my Rust implementation I am thinking to change the former API, mainly because to get multiple tokens from a string, I have to split the string every single time.
Thanks in advance
