Struct FileServiceServer 

pub struct FileServiceServer<T> { /* private fields */ }

Service gRPC definitions for the Hedera File Service (HFS).

Signature Requirements

The HFS manages file authorization differently, depending on type of file transaction, and this can be surprising.
The core element of file authorization is the keys field, which is a KeyList; a list of individual Key messages, each of which may represent a simple or complex key.
The file service transactions treat this list differently.
A fileCreate, fileAppend, or fileUpdate MUST have a valid signature from each key in the list.
A fileDelete MUST have a valid signature from at least one key in the list. This is different, and allows a file “owned” by many entities to be deleted by any one of those entities. A deleted file cannot be restored, so it is important to consider this when assigning keys for a file.
If any of the keys in a KeyList are complex, the full requirements of each complex key must be met to count as a “valid signature” for that key. A complex key structure (i.e. a ThresholdKey, or KeyList, possibly including additional ThresholdKey or KeyList descendants) may be assigned as the sole entry in a file keys field to ensure all transactions have the same signature requirements.
