pub fn limit(&self) -> u64
1.27.0 · sourcepub fn set_limit(&mut self, limit: u64)
pub fn set_limit(&mut self, limit: u64)
Sets the number of bytes that can be read before this instance will
return EOF. This is the same as constructing a new Take
instance, so
the amount of bytes read and the previous limit value don’t matter when
calling this method.
§Examples
1.15.0 · sourcepub fn into_inner(self) -> T
pub fn into_inner(self) -> T
Consumes the Take
, returning the wrapped reader.
