Struct MountParams 

pub struct MountParams { /* private fields */ }

Parses a comma-separated list of options of the form key or key=value or key="value". Commas and equals-signs are only permitted in the key="value" case. In the case of key=value1,key=value2 collisions, the last value wins. Returns a hashmap of key/value pairs, or EINVAL in the case of malformed input. Note that no escape character sequence is supported, so values may not contain the " character.

Examples

key0=value0,key1,key2=value2,key0=value3 -> map{"key0":"value3","key1":"","key2":"value2"}

key0=value0,key1="quoted,with=punc:tua-tion." -> map{"key0":"value0","key1":"quoted,with=punc:tua-tion."}

key0="mis"quoted,key2=unquoted -> EINVAL

Implementations

impl MountParams

pub fn parse(data: &FsStr) -> Result<Self, Errno>

pub fn keys(&self) -> impl Iterator<Item = &FlyByteStr>

pub fn get(&self, key: &[u8]) -> Option<&FlyByteStr>

pub fn get_as<T: FromStr>(&self, key: &[u8]) -> Result<Option<T>, Errno>

where <T as FromStr>::Err: Debug,

pub fn get_with<T, E: Debug>( &self, key: &[u8], parser: impl FnOnce(&str) -> Result<T, E>, ) -> Result<Option<T>, Errno>

pub fn remove(&mut self, key: &[u8]) -> Option<FlyByteStr>

pub fn is_empty(&self) -> bool

pub fn remove_mount_flags(&mut self) -> MountFlags

pub fn format_options(&self) -> FsString

Formats the mount parameters as comma-separated key[=value] pairs, with each option preceded by a leading comma (e.g. ,gid=3009,hidepid=2). The order is unspecified.
