Function pamoja_update_block_split 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_update_block_split(
    block: *const u8,
    block_len: usize,
    out_envelope_at: *mut usize,
    out_envelope_len: *mut usize,
    out_image_at: *mut usize,
    out_image_len: *mut usize,
) -> PamojaStatus

Reads a block back into the signed manifest and the image.

Arguments

• block - the block as it arrived.
• block_len - how many bytes it holds.
• out_envelope_at - receives where the signed manifest starts inside the block.
• out_envelope_len - receives how long it is.
• out_image_at - receives where the image starts.
• out_image_len - receives how long it is.

Returns

PamojaStatus::Ok on success. The two spans point into block itself, so nothing is copied and the caller keeps it alive.

Errors

Returns PamojaStatus::InvalidArgument for a null pointer, and PamojaStatus::Codec when the block does not carry this convention’s header.

Safety

block must be readable for block_len bytes and every non-null out pointer writable.
