Struct PackWriteLimits 

pub struct PackWriteLimits {
    pub compression_working_set: ByteBudget,
    pub decoded_object: ByteBudget,
    pub delta_base: ByteBudget,
}

Memory budgets for streaming pack generation.

Compression windows are admitted by these byte budgets, not by a fixed object count. A single object larger than Self::compression_working_set but within Self::decoded_object is written as an explicit one-object quantum. A single retained delta base may likewise exceed Self::delta_base and is kept alone. Either case is documented by the resulting working-set high-water mark; nothing else may silently exceed the configured budgets.

Peak charged memory is at most compression_working_set + delta_base plus one leftover lookahead object that did not fit the current window, and one oversized one-object quantum or retained base. The leftover is charged so decoded RAM cannot silently approach twice the working-set budget. Zlib output buffers and allocator slack are not included.

Fields

compression_working_set: ByteBudget

Decoded bodies plus per-object overhead admitted into one compression quantum.

decoded_object: ByteBudget

Hard cap on one decoded object body. Exceeding this is a typed limit error; the object is not treated as a one-object quantum.

delta_base: ByteBudget

Retained sliding-window delta-base bodies. Charged separately from the compression working set.
