Struct FieldRef 

pub struct FieldRef<'a> { /* private fields */ }

Immutable typed view over a field’s bytes.

Implementations

impl<'a> FieldRef<'a>

pub const fn new(data: &'a [u8]) -> Self

Create a field reference over the given byte slice.

pub const fn as_bytes(&self) -> &[u8]

Raw bytes of this field.

pub fn read_u8(&self) -> Result<u8, ProgramError>

Read a u8 from offset 0.

pub fn read_u16(&self) -> Result<u16, ProgramError>

Read a little-endian u16 from offset 0.

pub fn read_u32(&self) -> Result<u32, ProgramError>

Read a little-endian u32 from offset 0.

pub fn read_u64(&self) -> Result<u64, ProgramError>

Read a little-endian u64 from offset 0.

pub fn read_bool(&self) -> Result<bool, ProgramError>

Read a boolean from offset 0 (0 = false, non-zero = true).

pub fn as_address(&self) -> Result<&[u8; 32], ProgramError>

Borrow as a 32-byte address reference.

Trait Implementations
