ShareManagerLibrary - MetaVaults

This library helps pack multiple boolean flags and lockup durations into a compact uint256 bitmask. It enables efficient storage and quick access to share manager configuration in vault systems. Designed for the ShareManager component to control:

Whether minting, burning, or transfers are paused
Whether deposit/transfer whitelists are active
How long global or user-specific lockups last

All data is packed into a single uint256 using bit-level encoding for optimal storage and gas efficiency.

Bitmask Layout

Bit Range	Purpose
`[0]`	`hasMintPause` (bool)
`[1]`	`hasBurnPause` (bool)
`[2]`	`hasTransferPause` (bool)
`[3]`	`hasWhitelist` (bool)
`[4]`	`hasTransferWhitelist` (bool)
`[5..36]`	`globalLockup` (uint32)
`[37..68]`	`targetedLockup` (uint32)

Functions

`hasMintPause(uint256 mask) → bool`

Returns true if minting is paused (bit 0 is set).

`hasBurnPause(uint256 mask) → bool`

Returns true if burning is paused (bit 1 is set).

`hasTransferPause(uint256 mask) → bool`

Returns true if transfers are paused (bit 2 is set).

`hasWhitelist(uint256 mask) → bool`

Returns true if a deposit whitelist is enabled (bit 3 is set).

`hasTransferWhitelist(uint256 mask) → bool`

Returns true if a transfer whitelist is enabled (bit 4 is set).

`getGlobalLockup(uint256 mask) → uint32`

Returns the global lockup duration in seconds (timestamp), encoded in bits [5..36].

`getTargetedLockup(uint256 mask) → uint32`

Returns the targeted lockup duration in seconds, encoded in bits [37..68].

`createMask(IShareManager.Flags calldata f) → uint256`

Encodes the values in a Flags struct into a single bitmask:

struct Flags {
    bool hasMintPause;
    bool hasBurnPause;
    bool hasTransferPause;
    bool hasWhitelist;
    bool hasTransferWhitelist;
    uint32 globalLockup;
    uint32 targetedLockup;
}
