Struct bee_ternary::Trits [−][src]
#[repr(transparent)]pub struct Trits<T: RawEncoding + ?Sized = T1B1<Btrit>>(_);
Expand description
A type that represents a buffer of trits of unknown length.
This type is roughly analogous to [T]
or str
. It is an unsized type and hence is rarely
used directly. Instead, it’s more common to see it used from behind a reference (in a similar
manner to &[T]
and &str
.
Implementations
Interpret an (std::i8
) slice as a trit slice with the given encoding without first
checking that the slice is valid in the given encoding. The num_trits
parameter is used
to specify the exact length, in trits, that the slice should be taken to have. Providing a
slice that is not valid for this encoding is undefined behaviour.
Panics
This function will panic if num_trits
is more than can be represented with the slice in
the given encoding.
Safety
This function must only be called with an i8
slice that is valid for this trit encoding
given the specified num_trits
length. Right now, this validity is not well-defined and so
it is suggested that only i8
slices created from existing trit slices or trit buffers
be used. Calling this function with an invalid i8
slice is undefined behaviour.
Interpret a mutable (std::i8
) slice as a mutable trit slice with the given encoding
without first checking that the slice is valid in the given encoding. The num_trits
parameter is used to specify the exact length, in trits, that the slice should be taken to
have. Providing a slice that is not valid for this encoding is undefined behaviour.
Panics
This function will panic if num_trits
is more than can be represented with the slice in
the given encoding.

Interpret an (std::i8

that the slice is valid in the given encoding. The num_trits

This function will panic if num_trits
is more than can be represented with the slice in
the given encoding.
Interpret a mutable (std::i8

checking to ensure that the slice is valid in the given encoding. The num_trits
parameter
is used to specify the exact length, in trits, that the slice should be taken to have.
Panics
This function will panic if num_trits
is more than can be represented with the slice in
the given encoding.
Interpret this slice as an (std::i8
) slice.
Panics
This function will panic if the slice is not byte-aligned.
Fetch the trit at the given index of this trit slice without first checking whether the index is in bounds. Providing an index that is not less than the length of this slice is undefined behaviour.
This is perhaps the ‘least bad’ unsafe
function in this crate: not because any form of
undefined behaviour is better or worse than another (after all, the point of undefined
behaviour is that it is undefined) but because it’s the easiest to use correctly.
Safety
An index with a value less then the result of Trits::len
must be used. Any other value
is undefined behaviour.
Set the trit at the given index of this trit slice without first checking whether the index is in bounds. Providing an index that is not less than the length of this slice is undefined behaviour.

Fetch the trit at the given index of this trit slice, if the index is valid.
Set the trit at the given index of this mutable trit slice, if the index is valid.
Panics
This function will panic if the index is not less than the length of this slice.
pub fn iter(
&self
) -> impl DoubleEndedIterator<Item = T::Trit> + ExactSizeIterator<Item = T::Trit> + '_
pub fn iter(
&self
) -> impl DoubleEndedIterator<Item = T::Trit> + ExactSizeIterator<Item = T::Trit> + '_
Returns an iterator over the trits in this slice.
Using this function is significantly faster than calling Trits::get
in a loop and
should be used where possible.
Returns a subslice of this slice with the given range of trits.
Panics
This function will panic if called with a range that contains indices outside this slice, or the start of the range is greater than its end.
Returns a mutable subslice of this mutable slice with the given range of trits.
Panics
This function will panic if called with a range that contains indices outside this slice, or the start of the range is greater than its end.
Copy the trits from a trit slice into this mutable trit slice (the encoding need not be equivalent).
Panics
This function will panic if the length of the slices are different.
Fill this mutable trit slice with copied of the given trit.
Copy the contents of this trit slice into a new TritBuf
with the same encoding. This
function is analogous to to_vec
method implemented on ordinary slices.
pub fn chunks(
&self,
chunk_len: usize
) -> impl DoubleEndedIterator<Item = &Self> + ExactSizeIterator<Item = &Self> + '_
pub fn chunks(
&self,
chunk_len: usize
) -> impl DoubleEndedIterator<Item = &Self> + ExactSizeIterator<Item = &Self> + '_
Return an iterator over distinct, non-overlapping subslices of this trit slice, each with the given chunk length. If the length of the trit slice is not a multiple of the given chunk length, the last slice provided by the iterator will be smaller to compensate.
Panics
This function will panic if the given chunk length is 0
.
pub fn encode<U>(&self) -> TritBuf<U> where
U: RawEncodingBuf,
U::Slice: RawEncoding<Trit = T::Trit>,
pub fn encode<U>(&self) -> TritBuf<U> where
U: RawEncodingBuf,
U::Slice: RawEncoding<Trit = T::Trit>,
Encode the contents of this trit slice into a TritBuf
with a different encoding.
pub fn iter_trytes(
&self
) -> impl DoubleEndedIterator<Item = Tryte> + ExactSizeIterator<Item = Tryte> + '_
pub fn iter_trytes(
&self
) -> impl DoubleEndedIterator<Item = Tryte> + ExactSizeIterator<Item = Tryte> + '_
Returns an iterator over the trytes represented within this slice.
For encodings that are representation-compatible with trytes, such as T3B1
, use
Trits::as_trytes
instead since it is faster and more capable.
These functions are only implemented for trit slices with the T1B1
encoding because other
encodings are compressed and do not support handing out references to their internal trits.
T1B1
is an exception because its trits are strictly byte-aligned.
This fact also implies that T1B1
is the fastest encoding for general-purpose manipulation
of trits.
View this trit slice as an ordinary slice of trits.
View this mutable trit slice as an ordinary slice of mutable trits.
Return an iterator over distinct, non-overlapping mutable subslices of this mutable trit slice, each with the given chunk length. If the length of the trit slice is not a multiple of the given chunk length, the last slice provided by the iterator will be smaller to compensate.
Panics
This function will panic if the given chunk length is 0
.
Returns a mutable iterator over the trits in this slice.
Using this function is significantly faster than calling Trits::set
in a loop and
should be used where possible.
These functions are only implemented for trit slices with the T3B1
encoding because only
the T3B1
encoding has a representation compatible with a slice of Tryte
s. If you find
yourself commonly needing to convert between trits and trytes, T3B1
is the encoding to use.
