Struct MarginState 

pub struct MarginState {
    pub total_weighted_collateral: i128,
    pub total_weighted_liabilities: i128,
}

Aggregated margin state across all positions.

Computed once from all positions, then used to derive per-market withdraw/borrow limits and credit usage.

Fields

total_weighted_collateral: i128

Total weighted collateral in USDC base units.

total_weighted_liabilities: i128

Total weighted liabilities in USDC base units (always non-negative).

Implementations

impl MarginState

pub fn calculate(positions: &[PositionData<'_>]) -> MathResult<Self>

Calculate margin state from a set of positions.

For each position: applies strict oracle pricing, computes USDC value, applies IMF-adjusted weights, and accumulates into collateral/liabilities.

pub fn free_collateral(&self) -> u64

Free collateral = weighted collateral - weighted liabilities, clamped to 0.

pub fn credit_usage_bps(&self) -> MathResult<u64>

Credit usage in basis points (0 = no liabilities, 10_000 = 100%). Capped at 10_000 — an under-collateralized account is at 100% usage. Returns 0 if collateral is zero or negative.
