[−][src]Struct iso7816_tlv::simple::Tlv
SIMPLE-TLV data object representation.
Each SIMPLE-TLV data object shall consist of two or three consecutive fields: a mandatory tag field, a mandatory length field and a conditional value field
Methods
impl Tlv
[src]
pub fn new(tag: Tag, value: Value) -> Result<Self, TlvError>
[src]
Create a SIMPLE-TLV data object from valid tag and value.
A value has a maximum size of 65_535
bytes.
Errors
Fails with TlvError::InvalidLength
if value is longer than 65_535
bytes.
#[must_use]
pub fn tag(&self) -> Tag
[src]
Get SIMPLE-TLV tag.
#[must_use]
pub fn length(&self) -> usize
[src]
Get SIMPLE-TLV value length
#[must_use]
pub fn value(&self) -> &[u8]
[src]
Get SIMPLE-TLV value
#[must_use]
pub fn to_vec(&self) -> Vec<u8>
[src]
serializes self into a byte vector.
pub fn parse(input: &[u8]) -> (Result<Self, TlvError>, &[u8])
[src]
Parses a byte array into a SIMPLE-TLV structure. This also returns the unprocessed data.
pub fn from_bytes(input: &[u8]) -> Result<Self, TlvError>
[src]
Parses a byte array into a SIMPLE-TLV structure. Input must exactly match a SIMPLE-TLV object.
Errors
Fails with TlvError::InvalidInput
if input does not match a SIMPLE-TLV object.
