Struct ParametricWriteRange 

pub struct ParametricWriteRange {
    pub account_index: u8,
    pub base_offset: u32,
    pub stride: u32,
    pub cell_size: u32,
    pub count: u32,
    pub argument_index: u8,
    pub argument_name: &'static str,
    pub segment_name: &'static str,
}

A runtime-selected fixed-size cell inside a statically declared column.

The static WriteRange remains the conservative envelope used by tooling. This descriptor narrows that envelope for one invocation to base_offset + args[argument_index] * stride .. + cell_size.

Fields

account_index: u8

Instruction account-list index this column belongs to.

base_offset: u32

Absolute offset of element zero.

stride: u32

Byte distance between consecutive elements.

cell_size: u32

Writable bytes in the selected element.

count: u32

Number of cells in the column.

argument_index: u8

Index into the invocation’s bound u32 policy arguments.

argument_name: &'static str

Stable instruction-argument name for manifests and diagnostics.

segment_name: &'static str

Stable state segment/field name for manifests and diagnostics.
