Implementations§

source §

impl<T> ByteBuilder<T>

source

pub fn new() -> Self

Create an unconstrained Builder

source

pub fn new_fixed(size: NonZeroUsize) -> Self

Create a builder of fixed size

source

pub fn u8(self, v: u8) -> Self

Append an u8 in the builder

Examples found in repository ?

src/typed_bytes/builder.rs (line 78)

    pub fn iter8<F, I>(self, l: I, f: F) -> Self
    where
        I: Iterator + ExactSizeIterator,
        F: FnMut(Self, I::Item) -> Self,
    {
        assert!(l.len() < 256);
        let bb = self.u8(l.len() as u8);
        l.fold(bb, f)
    }

source

pub fn bytes(self, v: &[u8]) -> Self

Append bytes in the builder

Examples found in repository ?

src/typed_bytes/builder.rs (line 114)

    pub fn u16(self, v: u16) -> Self {
        self.bytes(&v.to_be_bytes())
    }

    /// Append an u32 in the builder
    pub fn u32(self, v: u32) -> Self {
        self.bytes(&v.to_be_bytes())
    }

    /// Append an u64 in the builder
    pub fn u64(self, v: u64) -> Self {
        self.bytes(&v.to_be_bytes())
    }

    /// Append an u128 in the builder
    pub fn u128(self, v: u128) -> Self {
        self.bytes(&v.to_be_bytes())
    }

source

pub fn fold<F, I>(self, l: I, f: F) -> Selfwhere
I: Iterator,
F: FnMut(Self, I::Item) -> Self,

fold over an iterator

source

pub fn iter8<F, I>(self, l: I, f: F) -> Selfwhere
I: Iterator + ExactSizeIterator,
F: FnMut(Self, I::Item) -> Self,

write an iterator of maximum 256 items using the closure F

note that the buffer contains a byte to represent the size of the list

source

pub fn iter16<F, I>(self, l: I, f: F) -> Selfwhere
I: Iterator + ExactSizeIterator,
F: FnMut(Self, I::Item) -> Self,

write an iterator of maximum 2^16 items using the closure F

note that the buffer contains 2 bytes to represent the size of the list

source

pub fn sub<F, U>(self, f: F) -> Selfwhere
F: Fn(ByteBuilder) -> ByteBuilder,

source

pub fn u16(self, v: u16) -> Self

Append an u16 in the builder

Examples found in repository ?

src/typed_bytes/builder.rs (line 92)

    pub fn iter16<F, I>(self, l: I, f: F) -> Self
    where
        I: Iterator + ExactSizeIterator,
        F: FnMut(Self, I::Item) -> Self,
    {
        assert!(l.len() < 65536);
        let bb = self.u16(l.len() as u16);
        l.fold(bb, f)
    }
