Struct AccountReader 

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

Header-aware read-only account reader.

Provides typed access to the header fields and a SliceCursor for the body.

Implementations

impl<'a> AccountReader<'a>

pub fn new(data: &'a [u8]) -> Result<Self, ProgramError>

Create a reader, validating minimum header size.

pub fn new_checked( data: &'a [u8], disc: u8, min_version: u8, layout_id: &[u8; 8], ) -> Result<Self, ProgramError>

Create a reader with full header validation.

pub fn header(&self) -> &AccountHeader

The underlying header, zero-copy.

pub fn discriminator(&self) -> u8

Discriminator byte.

pub fn version(&self) -> u8

Version byte.

pub fn flags(&self) -> u16

Flags as u16.

pub fn layout_id(&self) -> [u8; 8]

Layout ID (8 bytes).

pub fn body(&self) -> SliceCursor<'a>

Body data after the header as a cursor.

pub fn body_bytes(&self) -> &'a [u8]

Raw body bytes after the header.

pub fn raw(&self) -> &'a [u8]

Entire raw data including header.

pub fn u64_at(&self, offset: usize) -> Result<u64, ProgramError>

Read a u64 at a specific offset from the start of data.

pub fn address_at(&self, offset: usize) -> Result<&'a [u8; 32], ProgramError>

Read a 32-byte address at a specific offset.

pub fn overlay_at<T: Pod + FixedLayout>( &self, offset: usize, ) -> Result<&'a T, ProgramError>

Overlay a Pod type at a specific offset.
