If I have it right, its use is when you have a blob and you don't know the schema, but you know that the blob starts with a schema, and you proceed to deserialize the initial bytes of the blob into a BorshSchemaContainer type (or equivalent in another language).

Interestingly enough, replacing String::from("John Doe") with String::new() or String::from("") does not yield the error, but the program succeeds in this case with the name being set to an empty string. It contains data from multiple sources, including heuristics, and manually curated data. A Vec<u32> has to encode the length of the data since a Vec represents a variable size. The biggest pitfall/risk of Borsh, is that any change to the structure, might cause previous data to no longer be parseable. borsh-construct is an implementation of the Borsh binary serialization format for Python projects.

The Instruction::new_with_borsh function creates an Instruction by serializing a value with borsh. Thus, when you call any method, it fails to deserialize the existing state to the new structure. The problem is not that you're using a string, or a string in a struct, it's that you're using a string in a fixed-size array, hence the compiler pointing to A Decimal number implementation written in pure Rust suitable for financial calculations that require significant integral and fractional digits with no round-off errors. 3 Since Borsh is not a self-descriptive format we have a way to describe types serialized with Borsh so that we can deserialize serialized blobs without having Rust types available. 28. Conversely, you've designed your schema in JS as ['u32', 1] which is an array of length 1, so it does not need to encode a length since it is a fixed size. 0 Links; Homepage Since Borsh is not a self-descriptive format we have a way to describe types serialized with Borsh so that we can deserialize serialized blobs without having Rust types available.
