Strict or relaxed parser mode

[Luro02]

By default the parser should try to parse everything possible without erroring. Sometimes it might be useful to check for any malformed input/errors and this could be done by a "strict" flag?

// MasterPlaylist::parse(input: &str, strict: bool);
MasterPlaylist::parse(&input, true);

I would think that it would be better to have a parse_optioned method that takes an option struct.
Then there could be a parse method that is strict and a parse_relaxed that calls with differnt parameters of the option struct.

Would you mind giving an example or a function signature? (like in my post)

I understood it like this;

fn parse_optioned(input: &str, config: Option<Config>) -> crate::Result<_>;
fn parse(input: &str, config: Config) -> crate::Result<_>; // variable strictness?
fn parse_relaxed(input: &str) -> crate::Result<_>;
// this would call parse_optioned with `None`

I like the idea of having a Config, which can be used to configure the level of strictness. For example, you can ignore any unknown tags and error on a tag conflict?

I think of it like this

fn parse_optioned(input: &str, config: Config) -> Result<_>;
fn parse(input: &str) -> crate::Result<_> {
    parse_optioned(input, Config{/* Strict config */}
}
fn parse_relaxed(input: &str) -> crate::Result<_> {
    parse_optioned(input, Config{/* Relaxed config */}
}

Wouldn't this defeat the purpose, of having a Config? If there is a Config, it should be configurable by the user, for example like this;

fn parse(input: &str); // relaxed
fn parse_with(|config| {
   // edit config here
   config
});

In the example I provided the Cofig is user configurable. You could for example have a config builder or similar. But there are just default configs if tuning is not required. Den man. 23. sep. 2019 kl. 20.53 skrev Lucas <notifications@github.com>:
