Implementations

impl<'a> BlockWiseReader<'a>

pub fn new(r: Box<dyn Read + 'a>) -> Self

pub fn available_bytes(&self) -> usize

bytes from the current pos position to the end of the internal vector

pub fn size(&self) -> usize

overall size of the internal vector, is the same as available_bytes() + pos_get()

pub fn slurp(&mut self, bytecount: usize) -> Result<usize, Error>

Reads bytecount bytes from the stream and returns the amount of available bytes starting at pos, which can be more than bytecount when subsequently already read more, but also less if there were not enough available.

pub fn slurp_loop(&mut self, buffersize: usize) -> Result<usize, Error>

Reads bytes from the stream in buffersize steps as long as there are bytes available.

pub fn find(&self, e: u8) -> Option<usize>

pub fn search(&self, bytes: &[u8]) -> Option<usize>

pub fn pos_set(&mut self, pos: usize)

pub fn pos_add(&mut self, pos: usize)

pub fn pos_sub(&mut self, pos: usize)

pub fn pos_add_i(&mut self, pos: isize)

pub fn pos_cut(&mut self) -> Vec<u8>

removes all elements form the beginning of the internal vector to pos and returns the removed elements

pub fn pos_inject(&mut self, s: &[u8])

copies the data of the slice s at the position pos

pub fn get(&self) -> &[u8]

returns all data from pos to the end of the internal vector

pub fn get_back(&self, back: usize) -> &[u8]

returns all data from pos - back to pos of the internal vector

pub fn get_from(&self, pos: usize) -> &[u8]

returns all data from the given pos to the end of the internal vector

pub fn get_from_to_current(&self, pos: usize) -> &[u8]

returns all data from the given pos to the internal pos

pub fn slurp_match_repos(&mut self, marker_str: &[u8]) -> Result<bool, Error>

slurps as much as the marker_str is long and returns true if the content is the same as the marker_str, repositions the current position to the end of the marker

pub fn match_back(&self, marker_str: &[u8]) -> bool

matches a fixed string from pos - marker_str.len() to pos, returns true if matched

pub fn slurp_find_repos1( &mut self, bytecount: usize, e: u8 ) -> Result<bool, Error>

sets pos to find position position + 1 if found

pub fn slurp_find_repos0( &mut self, bytecount: usize, e: u8 ) -> Result<bool, Error>

sets pos to find position if found

pub fn pos_get(&self) -> usize

the current pos value

pub fn slurp_search_repos0( &mut self, bytecount: usize, bytes: &[u8] ) -> Result<bool, Error>

sets pos to find position if found

pub fn slurp_search_repos1( &mut self, bytecount: usize, bytes: &[u8] ) -> Result<bool, Error>

sets pos after find position if found
