WebIf you use a 8-Bit Processor, the natural size is 8Bit, but a int and enum are at least 16bit (without -fshort-enums), so you need there at least 2 registers which can slow down functions calls. – 12431234123412341234123 Sep 2, 2016 at 9:22 Add a comment 10 You can force it to be at least a certain size by defining an appropriate value.WebNov 14, 2024 · @mcarton In the above example,D(String) require most memory size,which is 24,so the size of enum is (24 + 8) = 32.If I replace the D(String) by D(Box), size of the enum can be reduced to 16.It is a great benefit if rust can tell me D(String) use 24 bytes, which is the max one of all variants,so the enum size should be 32 bytes,if the ...

WebMemory layout of a Rust enum. Before we proceed any further, let's look at the enum organization in memory. The size of the enum depends upon the largest variant. This example a Number::Complex requires two 64-bit floats. The total memory needed for the variant is 16 bytes. The size of the enum is 24 bytes. WebIt is strange idea but theoretically an array of byte enum-s will use 4x less memory than int-s. – i486 Sep 22, 2024 at 19:46 1 Definitely needs to be a byte, for example, if it's an Entity Framework entity property that you want to be a byte, and keeping it small is particularly important if it's part of a clustering key. – Triynko
WebSize of enum variable = 4 bytes Here, we are getting 4 because the size of int is 4 bytes. This makes enum a good choice to work with flags. How to use enums for flags?
